A Study on Performance of Al-Si alloy Bearing with SAE20W40 as Lubricants in Constant Load and Varying Speed Condition

Abstract: Bearing is used to carry radial loads of transmitting members in motion is called as journal bearing. Journal bearings are considered as essential components of all the rotating machinery. Various researchers carried out analysis particularly on copper based alloys published information related to Aluminium-Silicon alloy as a bearing material and relevant information are not available. So in the present work it has been selected to carry out the study on performance of the Aluminium-Silicon alloy bearing by considering the SAE20W40 grade lubricating oils as lubricating mediums and study has been carried out to find out the maximum pressure distribution by using a journal bearing test rig. The Al-Si alloy as test bearing and test lubricating oils SAE20W40 is run at different loads and speeds either by constant load and varying speed conditions (Example; 150N, 300rpm). It is made to run for 1hour to take maximum pressure value at angular rotation of 180̊. Sensor mounted on the bellow of the housing which gives the pressure readings and the data are transferred to the WINDOWS DUCOM 2010 software, extract condition of the bearings and gives the pressure distribution graphs as shown outcomes. In the results found by the graphs at all operating conditions of constant load and varying speed. The maximum pressure distribution of SAE20W40 grade oil is 1744kPa at 500 rpm. It can be conclude that the load carrying capacity and frictional force which acts on the journal and bearing material is safer, where frictional force decrease when speed increases.

Droplet impact dynamics on superhydrophobic surfaces with convex hemispherical shapes

Functional solid surfaces that can realize rapid shedding of liquid droplets have received significant research interest due to their close relevance to many industrial applications. Droplet impact on superhydrophobic surfaces with point-like protrusions has been demonstrated to take off as rings, which alters droplet impact dynamics and thus reduces contact time compared to flat surfaces. However, the essential role of the size ratio of protrusion-to-droplet (λ) for droplets impinging on such surface is rarely considered. Here, we numerically investigate droplet impact on superhydrophobic surfaces with convex hemispherical shapes using a phase-field model coupled with dynamic contact angles. The postimpact outcome regimes occurring for varied λ and Weber number (We) values, spanning 0 ≤ λ ≤ 1.44 and 0.69 ≤ We ≤ 33.68, are mapped on a We−λ diagram. Three distinct dynamic behaviours of droplet impact are identified: contactless bouncing, conventional bouncing, and ring bouncing. Detailed comparative analyses of these impact outcomes are also presented, including the evolution of droplet morphology, impact force, maximum impact pressure, pressure distribution, and velocity vector distribution. The results reveal a previously unknown phenomenon in contactless bouncing, where the impact force exhibits an initial increase followed by a subsequent decrease, while the maximum impact pressure remains approximately constant. Annular rotating retraction results in a longer contact time. Breakup occurs near the necked area, inducing a part of the droplet to depart from the surface as a jet. In addition, it is observed that the dimensionless maximum wetting area becomes independent of the λ and follows a scaling law of 0.67We3/5 if the We exceeds 2.75. Ring bouncing exclusively occurs within the range of 0.24 ≤ λ ≤ 0.96 and We ≥ 24.74, resulting in an approximate 50 % reduction in non-dimensional contact time compared to conventional bouncing. These findings favor the understanding of the underlying mechanisms governing droplet impact and thereby provide available guidance to the design of superhydrophobic surfaces.

Biomechanical effects of S1 sacroiliac screws versus S2 sacroiliac screws on sacroiliac screws combined with a lumbar iliac fixation in the treatment of vertical sacral fractures: a biomechanical finite element analysis

ObjectiveTo examine the impact of sacroiliac screw position and length on the biomechanical properties of triangular osteosynthesis in treating unilateral vertical sacral fractures and provide a clinical reference.MethodsUnilateral Denis type II sacral fractures were modelled using finite elements to represent Tile C pelvic ring injuries. Six sacroiliac screws were used with iliolumbar fixation patterns to fix the sacral fractures, and the sacral stability, maximum pressure, and stress distribution were compared among the internal fixation modalities.ResultsThe best vertical stability of the internal fixation model was achieved when the S1 segment was fixed with lengthened sacroiliac screws, followed by when the S1 segment was fixed using normal sacroiliac screws. There was no significant difference in vertical stability between the S1 + S2 dual-segment fixation model and the S1-segment fixation model. The maximum pressure under a vertical force of 600 N showed a trend of L5LS1 < L5NS1 < L5LS12 < L5LS2 < L5NS2 < L5NS12.ConclusionsIn unilateral vertical sacral fractures (Denis II) treated with triangular osteosynthesis using triangular jointing combined with unilateral iliolumbar + sacroiliac screw fixation, the use of a single lengthened sacroiliac screw for the S1 segment is recommended to achieve the best vertical stability of the sacrum with less maximum compression on the internal fixation components. If it is not possible to apply a lengthened sacroiliac screw, the use of a normal sacroiliac screw for the S1 segment is recommended. Adding an S2 screw does not significantly increase the vertical stability of the sacrum.

Influence of the skull bone and brain tissue on the sound field in transcranial extracorporeal shock wave therapy: an exvivo study.

Focused ultrasound is mainly known for focal ablation and localized hyperthermia of tissue. During the last decade new treatment options were developed for neurological indications based on blood-brain-barrier opening or neuromodulation. Recently, the transcranial application of shock waves has been a subject of research. However, the mechanisms of action are not yet understood. Hence, it is necessary to know the energy that reaches the brain during the treatment and the focusing characteristics within the tissue. The sound field of a therapeutic extracorporeal shock wave transducer was investigated after passing human skull bone (n=5) or skull bone with brain tissue (n=2) in this ex vivo study. The maximum and minimum pressure distribution and the focal pressure curves were measured at different intensity levels and penetration depths, and compared to measurements in water. Mean peak negative pressures of up to -4.97 MPa were reached behind the brain tissue. The positive peak pressure was attenuated by between 20.85 and 25.38 dB/cm by the skull bone. Additional damping by the brain tissue corresponded to between 0.29 and 0.83 dB/cm. Compared to the measurements in water, the pulse intensity integral in the focal spot was reduced by 84 % by the skull bone and by additional 2 % due to the brain tissue, resulting in a total damping of up to 86 %. The focal position was shifted up to 8 mm, whereas the basic shape of the pressure curves was preserved. Positive effects may be stimulated by transcranial shock wave therapy but damage cannot be excluded.

Numerical prediction of erosion due to a cavitating jet

We numerically investigate the erosion potential of a cavitating liquid jet by means of high-resolution finite volume simulations. As thermodynamic model, we employ a barotropic equilibrium cavitation approach, embedded into a homogeneous mixture model. To resolve the effects of collapsing vapor structures and to estimate the erosion potential, full compressibility is considered. Two different operating points featuring different cavitation intensities are investigated and their erosion potential is estimated and compared. Different methods are used for this purpose, including collapse detection (Mihatsch et al., 2015), maximum pressure distribution on the wall, and a new method of generating numerical pit equivalents. The data of numerical pit equivalents is analyzed in detail and compared with experimental data from the literature. Furthermore, a comprehensive grid study for both operating points is presented.

Reliability of OHM 3000 Plantar Pressure System for Measurement of Plantar Pressures in Healthy Indian Population

Purpose: The aim of this study is to determine intra and inter-session repeatability and reliability of OHM 3000 for reporting static and dynamic pressures in healthy Indian population. Methods: Using OHM 3000, twenty-eight healthy adults who did not present any gait abnormalities or musculoskeletal conditions were assessed one week apart for static and dynamic pressure. Bipedal stance test was used for assessing static variables- maximum pressure, average pressure, contact area, and weight distribution; whereas dynamic test was used for assessing dynamic variables- maximum pressure, average pressure, and contact area. Each participant performed three trials under supervision of each investigator. Results: Reliability was devised using ICC values and coefficient of variance for static and dynamic variables. ICC values for static and dynamic variables were reported to range between 0.88 to 0.94 and 0.61 to 0.98 respectively. Covariance values were reported to be lower than 13% in static and dynamic pressures recorded by both investigators. Conclusion: The study reports that OHM 3000 is a reliable device for assessing static and dynamic pressure in healthy adults demonstrating moderate to good reliability. KEYWORDS: Gait, Foot, Plantar Pressure.

Mixing Behavior and Pressure Drop Analysis of Micromixer with Different Geometric Conditions

A 3-D design of and analysis of fluid flow in the micromixer with different configurations is carried out in this dissertation. The main purpose of this research is to obtain minimum mixing length as rapid mixing is essential in many of the micro-fluidic systems used in biochemistry analysis, drug delivery, sequencing, or synthesis of nucleic acids. Also effect on various parameters such as mixing behavior, volume arrow, mixing length, maximum velocity, maximum pressure, pressure drop, and velocity distribution were analyzed by changing the mixing angle between inlets. Micromixers with square cross-section rectangular mixing chamber with various types of obstacle place in fluid flow paths such as rectangular obstacles, elliptical obstacle, and circular obstacle in split and recombination manner were designed for the analysis. The micromixer has 3 inlets and 1 outlet. Water and ethanol were used as working fluids. For computational fluid dynamics analysis, COMSOL Multiphysics 5.0 is used. From various results, we have found that size, the geometry of mixing chambers and obstacles, and mixing angle effect mixing length, pressure, and velocity. With a decrease in mixing angle mixing length, pressure drop, and maximum velocity decrease i.e it gives better mixing performance. Also with an increase in the number of obstacles mixing length and maximum velocity decreases and pressure drop increases. Micromixer with mixing angle 60 degree and circular obstacles gives minimum mixing length than any other models consisting rectangular or elliptical obstacle and mixing angle greater than 60 degrees.

Numerical Investigations on the Shape Optimization of Stainless-Steel Ring Joint with Machine Learning

Since pipes used for water pipes are thin and difficult to fasten using welding or screws, they are fastened by a crimping joint method using a metal ring and a rubber ring. In the conventional crimping joint method, the metal ring and the rubber ring are arranged side by side. However, if water leaks from the rubber ring, there is a problem that the adjacent metal ring is rapidly corroded. In this study, to delay and minimize the corrosion of connected water pipes, we propose a spaced crimping joint method in which metal rings and rubber rings are separated at appropriate intervals. This not only improves the contact performance between the connected water pipes but also minimizes the load applied to the crimping jig during crimping to prevent damage to the jig. For this, finite element analyses were performed for the crimp tool and process analysis, and the design parameters were set as the curling length at the top of the joint, the distance between the metal rings and rubber rings, and the crimp jig radius. Through FEA of 100 cases, data to be trained in machine learning were acquired. After that, training data were trained on a machine learning model and compared with a regression model to verify the model’s performance. If the number of training data is small, the two methods are similar. However, the greater the number of training data, the higher the accuracy predicted by the machine learning model. Finally, the spaced crimping joint to which the derived optimal shape was applied was manufactured, and the maximum pressure and pressure distribution applied during compression were obtained using a pressure film. This is almost similar to the value obtained by finite element analysis under the same conditions, and through this, the validity of the approach proposed in this study was verified.

Bilateral gait asymmetry associated with tibiotalocalcaneal arthrodesis versus ankle arthrodesis

BackgroundGait asymmetries have been reported following ankle arthrodesis. However, similar reports do not exist for tibiotalocalaneal arthrodesis (TTCA), which involves further articular fusion. This study aimed to assess the extent of gait asymmetry following TTCA when compared to ankle arthrodesis. MethodGait assessment was performed on 36 participants, including 12 ankle arthrodesis, 12 TTCA and 12 controls – using 3-D inertial sensors and pressure insoles. 48 gait parameters were monitored on both operated and non-operated sides. Questionnaires including AOFAS, FAAM, EQ-5D were used to assess both operative groups, comparatively. ResultsBoth operative groups reported significantly smaller stride, slower walking speed, altered stance phase with longer loading and shorter push-off compared to controls. Joint range of motion was significantly reduced on the operated side of both operative groups at hindfoot, forefoot and toe intersegments. However, the ankle arthrodesis group reported a significantly higher alteration compared to controls in maximum contact force and pressure distribution. Furthermore, bilateral comparison showed extended gait asymmetry in the ankle arthrodesis group with 29 out of 48 parameters being significantly different between the two sides, whereas only 16 out of 48 gait parameters showed bilateral difference in the TTCA group. ConclusionBoth ankle salvage operations led to significant gait alteration and bilateral asymmetry. However, extended joint restriction in TTCA does not seem to worsen the gait outcomes. Further investigation is needed to understand the long-term impact of altered gait, on neighboring joints, following TTCA.

Standard reference values of weight and maximum pressure distribution in healthy adults aged 18\u201365\u2009years in Germany

BackgroundThe aim of this study was to collect standard reference values of the weight and the maximum pressure distribution in healthy adults aged 18–65 years and to investigate the influence of constitutional parameters on it.MethodsA total of 416 healthy subjects (208 male / 208 female) aged between 18 and 65 years (Ø 38.3 ± 14.1 years) participated in this study, conducted 2015–2019 in Heidelberg. The age-specific evaluation is based on 4 age groups (G1, 18–30 years; G2, 31–40 years; G3, 41–50 years; G4, 51–65 years). A pressure measuring plate FDM-S (Zebris/Isny/Germany) was used to collect body weight distribution and maximum pressure distribution of the right and left foot and left and right forefoot/rearfoot, respectively.ResultsBody weight distribution of the left (50.07%) and right (50.12%) foot was balanced. There was higher load on the rearfoot (left 54.14%; right 55.09%) than on the forefoot (left 45.49%; right 44.26%). The pressure in the rearfoot was higher than in the forefoot (rearfoot left 9.60 N/cm2, rearfoot right 9.51 N/cm2/forefoot left 8.23 N/cm2, forefoot right 8.59 N/cm2). With increasing age, the load in the left foot shifted from the rearfoot to the forefoot as well as the maximum pressure (p ≤ 0.02 and 0.03; poor effect size). With increasing BMI, the body weight shifted to the left and right rearfoot (p ≤ 0.001, poor effect size). As BMI increased, so did the maximum pressure in all areas (p ≤ 0.001 and 0.03, weak to moderate effect size). There were significant differences in weight and maximum pressure distribution in the forefoot and rearfoot in the different age groups, especially between younger (18–40 years) and older (41–65 years) subjects.DiscussionHealthy individuals aged from 18 to 65 years were found to have a balanced weight distribution in an aspect ratio, with a 20% greater load of the rearfoot. Age and BMI were found to be influencing factors of the weight and maximum pressure distribution, especially between younger and elder subjects. The collected standard reference values allow comparisons with other studies and can serve as a guideline in clinical practice and scientific studies.

Influence of squeegee impact on stencil printing process: CFD approach

This work has been conducted to predict the real time observation of solder paste Sn96.5Ag3.0Cu0.5 (SAC305) filling process into stencil apertures as well as print quality in stencil printing by using Computational Fluid Dynamics (CFD) approach. A 3-Dimensional stencil printing model was developed and simulated in FLUENT by using different squeegee parameters which are the angle and printing speed. An experimental work was performed to be compared with part of the simulation results in term of print quality for validation purpose. It is found that squeegee angle 60° to 80° has potential to obtain good print quality of solder paste. In addition, print speed range between 35 mm/s to 95 mm/s also can be the good print speed option to achieve good print quality in stencil printing process. Finally, the maximum pressure distribution of solder paste also changes substantially as the squeegee travel further with respect to different values of tested parameters.

Investigation on Effecting Parameters of the Wind Disturbance on Stability of the Steering System

In self-driving vehicles, it is necessary to control the steering system fully. In this paper, the pressure and the velocity distributions on the surface of the vehicle’s body under the influence of wind have been studied at different angles (35°, 90°, and 125°). The parameters that affect the steering system of the self-driving vehicle have been studied, affected by another vehicle (SUV) using the CFX ANSYS (18.2) and the SOLIDWORKS simulation programs. The torque and the effort have been calculated on the steering system by using the mathematical equation in the MATLAB program. The results have showed the highest torque and the effort values when the wind has faced the car at an angle of 125 degrees and the highest drag value when the vehicle has been in front of the SUV. The maximum pressure distribution is recorded when the air is 90 degrees. The highest effort is on the steering wheel when the SUV is next to the vehicle.

A Study of The Effect of Loaded Pile Groups on Neighboring Fuel Storage Tanks

This work examines the interaction between two neighbouring structures, a fuel storage tank and a nearby pile group when the pile group is placed under static loads with different loading conditions related to the tank status (empty, half full, and full). Due to the role of soil in transferring load between embedded neighbouring structures, this study deals with soil-structure interaction by assuming that the soil displays nonlinear behaviour. The major factors which play a significant role in the response of the fuel storage tank were thus considered; these factors were defined as the maximum bending moment along the tank wall, the maximum shear force along the tank wall, the hoop stress in all rings of the tank, the maximum pressure distribution along the tank wall, and the maximum lateral displacement along the tank wall. The influence of the distance between these structures on bending moment, shear force, and hoop stresses in the fuel storage tank were also studied. The results suggest that the case of a full liquid storage tank represents a critical state that must be considered when assessing the structural behaviour of the storage tank.

Plantar pressure distribution during standing in women with end-stage hip osteoarthritis

BackgroundPatients with hip osteoarthritis (OA) experience abnormal movement patterns and reduced loading of the affected leg. The plantar contacts the ground and receives force from the ground. Plantar pressure distribution may differ in patients with hip OA compared to healthy adults and may influence physical functioning in these patients. Research questionWe investigated whether plantar pressure distribution during standing differed between patients with hip OA and healthy adults. We also analyzed the relationship between plantar pressure distribution and walking ability and the factors affecting plantar pressure distribution. MethodsMaximum plantar pressure distribution during standing for 20 seconds was investigated in patients with hip OA (n = 62; OA group) and in healthy adults (n = 53; Control group). Statistical comparisons between these groups were made using Fisher’s exact test and residual analysis. In the OA group, leg length discrepancy, range of hip extension, leg loading, knee extensor strength, and 10 m walking time were assessed; multiple linear regression and logistic regression analyses were used to examine the relationships between these factors and maximum plantar pressure distribution. ResultsMaximum plantar pressure distribution was different between the OA and control groups. In the OA group, maximum plantar pressure distribution was one of the significant predictors of 10 m walking time. Additionally, leg length discrepancy was a significant predictor of maximum plantar pressure distribution in this group. SignificanceDuring standing, the proportion of patients for whom the maximum plantar pressure region was the heel tended to be lower in the group with hip OA compared to the healthy adults. Plantar pressure distribution may have an importance for evaluating walking ability in patients with hip OA. Correcting leg length discrepancy and loading under the heel could adjust plantar pressure distribution in patients with hip OA.

The effects of fatigue on plantar pressure and balance in adolescent volleyball players with and without history of unilateral ankle injury

Summary The purpose of this study was to assess plantar pressure and static balance alterations after jumping and landing. According to the importance of devastating impact of improper distribution of plantar forces on the incidence of abnormal movements and stresses in the foot structure of volleyball players, studying the effect of fatigue on plantar pressure and static balance can lead to significant achievements in the evaluation of this organ's performance. In this study, 12 male adolescent volleyball players with a history of unilateral ankle injury and 12 male adolescent volleyball players without a history of unilateral ankle injury was participated. Plantar pressure characteristics and static balance in volleyball players with and without history of unilateral ankle injury was recorded before and after a fatigue from consecutive jumping and landing protocol while standing static on foot pressure. maximum pressure, mean pressure, pressure distribution, surface and romberg open and close eyes balance registered. There was a significant difference between the maximum and the mean plantar pressure and the contact surface of the right foot before and after fatigue and significant difference between the mean pressure and the pressure distribution of the healthy foot and the injured leg in individuals with a history of ankle injury also fatigue cause reduce balance in adolescent volleyball players without history of unilateral ankle injury in open eyes mode and reduce balance in adolescent volleyball players with history of unilateral ankle injury in open and closed eyes. These changes could lead to lower limb injuries.

Performance Study of Conical Hydrodynamic Bearing Under Different Semi Cone Angle on Conical Hydrodynamic Bearing Performance With Air Lubrication

Bearing plays crucial role in the functioning of almost all industries such as chemical, petrochemical, automotive, and various process industries. Bearing supports, guides, and reduces the friction of moving machine parts. The lubrication in fluid film journal bearing is used to separate two relatively sliding surfaces with a thin film. The fluid wedge between shaft and bearing causes pressure built to support the load. Conical bearing supports load in both axial and radial direction over separate cylindrical journal bearing and thrust bearing. Conical bearing replaces two bearings with one. The present study related to performance analysis of conical hydrodynamic bearing with air as lubricant. In this paper, semi-cone angle effect is analyzed on the pressure distribution of air lubricated conical bearing. The performance is carried out with semi cone angle of 5, 10, 20, 45, 60 and 80 degrees using ANSYS workbench. Results shows maximum pressure distribution is obtained for the semi cone angle between 5 to 10. Bearing load capacity in radial direction reduces after 450 angle.

Reconstruction of radial parametric pressure field near ground surface of landing typhoons in Northwest Pacific Ocean

The radial distribution of environmental pressure near the ground surface during typhoons is an initial input condition for height-resolving typhoon modeling widely used as a practical and relatively accurate method for rapid assessment of typhoon-induced natural hazards and wind-resistant design of structures. The radius to maximum wind speed Rmax and radial pressure distribution parameter βs, (usually named the Holland power exponent of atmospheric pressure) are two key pressure field parameters that fundamentally determine the parametric typhoon pressure field and collocated wind velocity field. Observations from the Joint Typhoon Warning Center (JTWC) show that Rmax follows a lognormal distribution and has strong correlation with central pressure difference Δps and typhoon center latitude ψ. However, it is still hard to satisfactorily reproduce the landing typhoon environmental pressure. By employing near-ground environmental pressure data involving several hundreds of meteorological stations distributed in coastline regions of the Northwest Pacific Ocean, evolution of typical environmental pressures during four strong typhoons, Khanun (0515), Wipha (0713), Krosa (0716) and Morakot (0908), have been recorded in Southeast China. Finally, a novel technique for modeling the radial surface pressure model is proposed utilizing an appropriate model for radius to maximum winds Rmax. The variation characteristics for directions, landfall states and probability distributions of βs are compared and discussed, and then probability correlations among βs and Rmax, Δps, ψ are fitted and validated, showing that the statistical correlation function model is obviously different from former formulations and is more suitable for rebuilding a wind velocity field, especially near the ground surface after typhoon landfalls along the southeast coastlines of China, which are typhoon-prone hazard regions during moving typhoons.

Investigation of impact craters on flat surface of cylindrical targets based on experiments and numerical simulations

We carried out impact experiments using cylindrical gypsum targets with various radii and investigated the crater on the top (flat) surface. At a ratio of projectile and target radii ∼1/20, the crater size abruptly increases; the spallation extends to the side surface of the targets. The results are closely similar to the previous ones on the curved surfaces. A shock wave propagation model, introduced by Suzuki et al. (2018, Icarus 301, 1–8), can represent such results as the steep increase of the size of the spallation zone in both cases of spherical and cylindrical targets. Using this model, the maximum fragment size is evaluated and agrees well with the experimental results. We found that the enlargement of the spallation zone is crucial to the transition from cratering to catastrophic disruption. We also carried out numerical calculations with iSALE code capable of simulating impact processes in solid materials. The maximum pressure distribution shows that the most parts of the spallation zone are not metamorphosed by shock waves. Also, the crater depth is represented by iSALE without damage models, while the “spallation” seems not to be well reproduced by iSALE even with the damage models.

Probability Analysis of the Wave-Slamming Pressure Values of the Horizontal Deck with Elastic Support

This paper presents the probability distribution of the slamming pressure from an experimental study of regular wave slamming on an elastically supported horizontal deck. The time series of the slamming pressure during the wave impact were first obtained through statistical analyses on experimental data. The exceeding probability distribution of the maximum slamming pressure peak and distribution parameters were analyzed, and the results show that the exceeding probability distribution of the maximum slamming pressure peak accords with the three-parameter Weibull distribution. Furthermore, the range and relationships of the distribution parameters were studied. The sum of the location parameter D and the scale parameter L was approximately equal to 1.0, and the exceeding probability was more than 36.79% when the random peak was equal to the sample average during the wave impact. The variation of the distribution parameters and slamming pressure under different model conditions were comprehensively presented, and the parameter values of the Weibull distribution of wave-slamming pressure peaks were different due to different test models. The parameter values were found to decrease due to the increased stiffness of the elastic support. The damage criterion of the structure model caused by the wave impact was initially discussed, and the structure model was destroyed when the average slamming time was greater than a certain value during the duration of the wave impact. The conclusions of the experimental study were then described.
