Analysis of Power Losses and Experimental Method for Determining Resistance in Electric Elevators

To be able to carry out a high-quality analysis of the operation and design of elevator systems with a driving pulley, it is necessary to determine the size of the losses that occur in the drive mechanism and elevator guide rails. The paper defines an experimental procedure for determining the losses and the efficiency coefficient of elevator facilities depending on the relative load of the cabin in operational conditions. The experiment was carried out on a passenger elevator with a rated load of 320 kg and a lifting height of 28 m. An analysis of the resistance, i.e., the source of power losses in vertical lifting devices, was performed, the most significant of which occur and are especially pronounced in worm gear reducers and on the guiding system of the cabin and counterweight, where the type of guiding elements also has an influence. A particular problem is expressed due to the changing state of the contact surfaces (between the guide rails and the guide shoes) during exploitation and the eccentric loading of the cabin. Also, the paper analysed the obtained measurement results to determine the dependence of the efficiency coefficient of the facility concerning the relative load of the cabin.

Research on photovoltaic water pumping system based on valve opening model

Photovoltaic water pumping system (PVWPS) is an important way to use solar energy. In order to further improve the solar energy utilization rate of PVWPS, this study proposes a valve opening model, which solves the problem of more solar energy waste caused by fixed pipeline characteristics under different irradiation intensities. Firstly, the theoretical calculation formula of pipeline flow is deduced according to the balance relationship between photovoltaic energy supply and energy demand of water lifting pipeline in PVWPS, and its working principle is expounded. Finally, the function model of pipeline flow-valve opening-radiation intensity is derived from the cycle test of PVWPS, and the PVWPS with water lifting height of 10 m, 12 m and 14 m is verified by all-day test. Compared with the unregulated valve, the cumulative water extraction of the PVWPS with three water lifting heights after valve regulation is increased by 15.85 %, 18.06 % and 80.71 % respectively, indicating that the cumulative water extraction of the PVWPS can be effectively improved by adjusting the valve opening. This study provides a new idea for improving the utilization rate of solar energy in PVWPS.

Application of KH-RT model in lifting flame of methanol jet atomization

Abstract For the methanol jet atomization in a co-flow gas lifting flame, the self-developed WAVE model and KH-RT model were employed using the Saturne program to simulate the primary breakup of the jet column and the atomization of spray particles. Additionally, the unsteady flamelet model was utilized to simulate the combustion process. Comparing the calculated flame lifting height, droplet diameter distribution, and velocity distribution with experimental results demonstrates the atomization model’s ability to accurately capture the methanol fuel atomization process. This comparison verifies the reliability of both the atomization and combustion models, indicating their high accuracy. The study shows that upon injection from the nozzle, methanol fuel rapidly diffused, creating a cone-shaped spray structure. The high concentration of OH radicals is located close to the boundary between the regions of OH radical distribution and methanol distribution, gradually spreading downstream of the methanol jet. Furthermore, an increase in fuel flow rate resulted in a reduction in the flame’s lift height.

Hydrogen in the Natural Gas Network—Relevance for Existing Fire Precautions

Power-to-gas technology can be used to convert excess power from renewable energies to hydrogen by means of water electrolysis. This hydrogen can serve as “chemical energy storage” and be converted back to electricity or fed into the natural gas grid. In the presented study, a leak in a household pipe in a single-family house with a 13 kW heating device was experimentally investigated. An admixture of up to 40% hydrogen was set up to produce a scenario of burning leakage. Due to the outflow and mixing conditions, a lifted, turbulent diffusion flame was formed. This led to an additional examination point and expanded the aim and novelty of the experimental investigation. In addition to the fire safety experimental simulation of a burning leakage, the resulting complex properties of the flame, namely the lift-off height, flame length, shape and thermal radiation, have also been investigated. The obtained results of this show clearly that, as a consequence of the hydrogen addition, the main properties of the flame, such as lifting height, flame temperature, thermal radiation and total heat flux densities along the flame, have been changed. To supplement the measurements with thermocouples, imaging methods based on the Sobel gradient were used to determine the lifting height and the flame length. In order to analyze the determined values, a probability density function was created.

Effects of Z-axis lifting height on porosity and microstructure by blue laser directed energy deposition

The Z-axis lifting height is significant in layer-by-layer fabrication using laser directed energy deposition (L-DED). In this paper, we have deeply examined the porosity and grain morphologies in the double layers of AlSi10Mg by blue laser directed energy deposition (BL-DED). After the deposition of a single track, the depositional head was raised by a certain Z-axis lifting height and then a second layer was deposited. As the Z-axis lifting height increases, the quantity density of pores in the second layer increases, leading to higher porosity. Especially, the boundary of the overlapping area exhibits the highest porosity, measuring 0.84%. The Z-axis lifting height can be set lower than the height of a single track, while maintaining high dimensional accuracy and surface quality.

ОЦЕНКА УСТОЙЧИВОСТИ ОБШИВКИ БОКОВЫХ СТЕН И КРЫШИ КУЗОВА ПАССАЖИРСКОГО ВАГОНА ПРИ ВЫПОЛНЕНИИ РЕМОНТНЫХ РАБОТ

The lining stability of the side walls and roof of the passenger car body is assessed during repair work related to its asymmetric lifting with a jack at one end of the body. Using mathematical modeling, the lifting height is determined which is necessary to ensure the possibility to dismantle the springs of the spring set of the central suspension. The stability of the reinforced lining of the car body was assessed using the developed problem-oriented elastic-dissipative finite element model of the supporting structure of the passenger car body. The calculations are performed in a static non-linear formulation, taking into account the geometric nonlinearity and non-conservativeness of the operating loads. The stability of the reinforced load-bearing lining of the car was assessed both for the initial structure and for a structure with geometric imperfections such as technological loss. The analysis of the research results allows to conclude that during the technological operation associated with lifting the passenger car body with a jack under one support, it can lead to a loss of stability of the sill belt lining of the side wall and the smooth sheathing of the roof slope. The results obtained agree with the results of the inspection of full-scale cars in operation.

On the Formation and Accuracy of the Implementation of the Program Modes of Movement of Mobile Robots with Walking Propulsion Devices

Various kinematic schemes of walking propulsion devices of mobile robots are considered. Among them there are cyclical mechanisms with a different number of links, zoomorphic, insectomorphic, orthogonal and others. Propulsion devices may differ from each other in the number of drives. Examples of walking machines and laboratory samples with such propulsion devices are given. The importance and significance of the tasks of ensuring the accuracy of positioning the foot of the propulsion device as the working body of the walking mechanism, due to the need to place it on the supporting surface at a given point when moving the propulsion device, are substantiated. It is also necessary to overcome obstacles identified by the information-measuring system and having certain dimensions and located in certain places on the support surface. Such a movement should be accompanied by a minimum of the height of the foot lift, which ensures a minimum of energy consumption. Additionally, the necessity of ensuring the required speed of the foot of the propulsion devices walking mechanism in the phase of its interaction with the support surface is justified, which is explained by maintaining the same speeds of the support feet in the relative heading movement in the phase of the implementation of the traction force. Even with a slight difference in the speeds of the support stops, the traction force is developed only by the propulsion device, whose foot moves at maximum speed. The remaining propulsion devices operate in braking mode. Compensation is possible only due to the rigidity of the static characteristics of the engine and the viscous-elastic-plastic properties of the soil. In this case, an increased load is imposed on the drive motors and therefore energy efficiency is reduced. The problem of assessing the accuracy of positioning is solved by known methods by introducing the transfer functions of the stepping mechanism. The transfer functions link the movement of the output element of the motor of the corresponding drive and the working body of the walking mechanism — the foot. To solve the problem of estimating the accuracy of the walking mechanism by the speed of the foot, new transfer functions are introduced, which are components of the new matrix. Their characteristic feature is the dependence on the speeds of the output elements of the executive motors. The equation of motion providing optimality in positioning accuracy and speed is obtained.

Facilitating safe and sustained submucosal lift through an endoscopically injectable shear-thinning carboxymethyl starch sodium hydrogel

Traditional submucosal filling materials frequently show insufficient lifting height and duration during clinical procedures. Here, the anionic polysaccharide polymer sodium carboxymethyl starch and cationic Laponite to prepare a hydrogel with excellent shear-thinning ability through physical cross-linking, so that it can achieve continuous improvement of the mucosal cushion through endoscopic injection. The results showed that the hydrogel (56.54 kPa) had a lower injection pressure compared to MucoUp (68.56 kPa). The height of submucosal lifting height produced by hydrogel was higher than MucoUp, and the height maintenance ability after 2 h was 3.20 times that of MucoUp. At the same time, the hydrogel also showed satisfactory degradability and biosafety, completely degrading within 200 h. The hemolysis rate is as low as 0.76 %, and the cell survival rate > 80 %. Subcutaneous implantation experiments confirmed that the hydrogel showed no obvious systemic toxicity. Animal experiments clearly demonstrated the in vivo feasibility of using hydrogels for submucosal uplift. Furthermore, successful endoscopic submucosal dissection was executed on a live pig stomach, affirming the capacity of hydrogel to safely and effectively facilitate submucosal dissection and mitigate adverse events, such as bleeding. These results indicate that shear-thinning hydrogels have a wide range applications as submucosal injection materials.

Statics Analysis of a New Type of Wheeled Wind Crane

Under the background of the goal of "carbon peak, carbon neutrality", China's wind power development gradually transfers from the three northern regions to the central and eastern parts of the south, wind power installed capacity continues to increase, wind turbine height and single capacity continue to improve, while facing complex geographical environments such as mountains, forest areas, fish ponds, farmland, the functional demand for wind turbine hoisting equipment is increasing day by day. Due to the backwardness of China's metal material manufacturing technology and large wind power crane detection technology, the fatigue life of wind power crane is unpredictable, often in dangerous working conditions and negative loads, resulting in boom fatigue damage, which has a significant impact on personnel safety and national and company economic losses. Today, the demand for wind power has increased greatly, and the wind motor has changed from the previous slow speed, small wind blades and light weight to the single machine capacity is getting larger and larger, the blades are getting longer and longer, the tower height is getting higher and higher, and the lifting parts are getting heavier and heavier. This has created the characteristics of high, large and heavy wind turbines today. Therefore, the traditional wind turbine hoisting equipment has been unable to meet the needs of wind power construction, such as the all-ground crane high cost, weak wind resistance; Crawler crane lifting weight and lifting height is insufficient, and the site required for installation and demolition is large; The traditional tower crane needs to be attached to the tower barrel, which has low disassembly efficiency and great influence on the tower barrel, which seriously restricts the rapid development of wind power construction. Therefore, it is urgent to develop wind power cranes that can better adapt to complex geographical environments, ultra-high towers, and large megawatt units, while reducing installation costs and improving the safety and efficiency of hoisting, it is necessary to carry out mechanical analysis of wind power crane equipment. In order to ensure the reliable operation of the wind power crane, improve the utilization rate, extend the service life of the equipment, prevent potential production safety hazards, and reduce equipment maintenance costs, it is necessary to master its static performance through theoretical analysis and calculation, in order to propose and implement the design optimization and improvement program and the later use and maintenance measures. Due to overload, cracks, fatigue and corrosion, various failures caused by wind power cranes may reduce or lose their pre-designed functions and roles. Therefore, it is necessary to deeply analyze the static performance of the crane, find the largest dangerous force parts, eliminate potential safety hazards, and ensure its safe, stable and reliable operation, to monitor such complex structural parts is not only time-consuming, and may not be able to truly detect the safety hazards. In order to solve these problems, ANSYS (finite element analysis software) is used to analyze the theoretical stress of the 3D structure model, and the theoretical dangerous stress position of the structure is solved. Provide strong data support for the design and development of wind power crane industry in the later stage

Experimental study on strain and stress of steady device in a catenary for a high-speed railway

Steady device is an important component in a catenary for a high-speed railway. It plays an important role in ensuring the current collection quality and stable and reliable operation of the train. In this paper, the strain distributions of positioner tube, column and pin sleeve in the positioning device are measured by strain gauges in our laboratory, and the variation laws of axial and transverse strains, and axial stresses of the three key components under different horizontal and oblique loads, and lifting heights of positioner are studied and analyzed. It is found that the strains and axial stresses of all measuring points basically have a linear relationship with the horizontal load, which are little affected by the oblique load. There is an ‘arch’ change law between these strains/stresses and the lifting height of positioner. For the stresses of two measuring points at the same section, the tensile stress is generally higher than the compressive stress. The maximum tensile stress occurs on positioner tube, which is the weakest part. This work provides the technical support for the material selection, structural design and detection of the positioning device.

STRUCTURAL OPTIMIZATION OF JET PUMP BASED ON BP NEURAL NETWORK

With the increasing drilling depth, problems follow, such as the lifting height of the liquid in the well and increased pump operation. Therefore, improving the production efficiency of deep wells is a hot spot in the current oil drilling and production industry. This paper designs a new jet pump that can be mined for high and low-pressure oil layers according to the oil wells’ inter-layer contradiction. The FLUENT software is used to simulate the new jet pump, analyze the pump efficiency factors of the jet pump and the physical properties of the fluid, and the BP neural network is used to optimize the structure of the jet pump.

Forklift selection by multi-criteria decision-making methods

A forklift is a very important and common equipment for transporting materials in many different locations such as workshops, warehouses, supermarkets, etc. This equipment has the effects of reducing labor consumption of workers, ensuring the safety of goods and improving labor efficiency. That is why forklift selection is very important. In order to choose a forklift, it is necessary to consider many parameters such as lifting capacity, lifting height, travel speed, safety level, price, maintenance cost, level of impact on the environment, ease of use, etc. However, today there are many types of forklifts on the market, these forklifts have different specifications and prices, making it difficult for shoppers to choose a product in many available types. This study has applied multi-criteria decision-making (MCDM) methods for forklift selection. Two MCDM methods having been used are the COCOSO (Combined Compromise Solution) method and PIV (Proximity Indexed Value) method. Two different methods having also been used to calculate the weights for the criteria are the ENTROPY method and MEREC (Method based on the Removal Effects of Criteria) method. The selection of the best type of forklift applies to the six available types. Six criteria having been used to describe each alternative are lifting height, maximum lifting height, minimum lifting height, fork length, fork width, and price. Each MCDM method will be used in combination with two weight methods. Thus, the ranking results of forklifts are shown in four different series of numbers. An amazing result has occurred that the best and worst forklifts have been consistently determined to be the same in all cases examined. This is the outstanding advantage of the COCOSO and PIV methods compared to other MCDM methods.

Interaction of conical monolithic thin-walled reinforced concrete shells with the soil of the foundation

Conical monolithic thin-walled reinforced concrete blocks (shells) can be used as foundations for frame structures and buildings with load-bearing walls. As an analogue of columnar foundations, this type has the advantage of the speed of installation. It almost wholly excludes earthwork and formwork from the technological process, provided that the physical and mechanical properties of the soil base are improved. Shells are immersed in the supporting soil base with the help of dynamic or static loading. Additional soil base compaction occurs due to interaction with the conical outer surface of the shells. The work aims to develop the theoretical foundations for modelling, mathematical description and the possibility of optimizing the process of sinking monolithic thin-walled spatial reinforced concrete shells that model foundations for low-rise technological or residential facilities. Based on the analysis of the ”hammer-head-shell-soil” system, an elastic-viscous-plastic model with an attached soil mass was developed and presented, which is used as a basis for developing a system of nonlinear differential equations of the second order. The article provides recommendations on the impact of structural and technological factors on the failure rate and the contact stresses in the hammer-shell zone. The following factors have a significant influence on the failure of the shell: the height of the hammer lift, soil resistance, and the ratio of the masses of the hammer and the shell. The effect of shock-absorbing elements is insignificant. The greatest influence on the magnitude of the contact forces in the zone of the hammer-shell has: the height of the fall of the hammer and the stiffness of the resilient gasket.

The influence of transfer distance and pace of work on foot positioning strategies and low back loading in a manual material handling task

Foot positioning strategies are a key parameter in manual materials handling. The objective of this study was to assess the effects of transfer distance, pace and foot positioning on low back loading. Sixteen handlers performed a free handling task with conditions of pace (self-selected and 25% faster), distance (1.5 m, 1.0 m and 0.5 m), height (near-ground and above-waist levels), and mass (10 kg and 20 kg). A linear mixed model was used to evaluate the effects of mass, distance, pace and height on foot positioning occurrences. A non-parametric test (nparLD) was used to evaluate the effects of Pace × Foot positioning and Distance × Foot positioning on L5/S1 sagittal and asymmetrical moments. Positioning the feet aside from the lifting pallet was more prevalent when transferring at shorter transfer distances, high lifting height, and faster pace. When the feet were oriented aside the lifting area, asymmetrical peak moments were slightly higher when transferring at short distance. Facing the lifting pallet may ensure load symmetry, but orienting the feet aside may help to adapt to fast pace or short transfer distance.

The purpose of research The aim of the study is to estimate the maximum transmission range of video information of various quality from an unmanned aerial vehicle to predict its capabilities when monitoring an emergency situation. Methods. Research methods are based on the concepts of the theory of radio electronics, the theory of diagnostics and prognostics of the technical condition of unmanned aerial vehicles. The methods of multicriteria analysis, parametric and structural synthesis were used. The principles of transmitting video information from unmanned aerial vehicles used to monitor emergency situations are analyzed. A critical assessment of the maximum transmission range of video information from unmanned aerial vehicles during emergency monitoring has been made. Results. Graphs of the dependence of the energy reserve in the radio communication line between the unmanned aerial vehicle and the ground control system have been obtained, allowing to estimate the maximum values of the transmission range of video information of various quality in the 2.4 and 5.8 GHz bands when monitoring emergencies. The maximum line-of-sight range between the UAV and the UAV slightly depends on the lifting height of the antenna of the mobile UAV and at the lifting height of the UAV from 100 to 500 m is from 40 to 85 km. The maximum range of HD quality video transmission with the FM-4 UAV using Turbo 7/8 turbocoding in the 2.4 and 5.8 GHz bands is 3 and 7 km, respectively, and when transmitting FHD quality video information with the CAM-16 UAV using Turbo 7/8 turbocoding in the 2.4 and 5.8 GHz bands is 1.4 and 3.3 km. Conclusion. The development of a method for determining the maximum transmission distance of video and command-telemetry information allows for a more accurate assessment of the energy reserve in the radio communication line with an unmanned aerial vehicle. Unmanned aerial vehicles for direction finding and detection of rescue beacons of victims during search and rescue operations should be considered as promising areas of research in the field of the use of unmanned aerial vehicles in emergency situations.

Effects of Single Noninvasive Spinal Cord Stimulation in Patients with Post-Stroke Motor Disorders

Post-stroke gait disorders are often characterized by abnormal kinematic and kinetic patterns, deviations in spatiotemporal features, altered muscle activation, and increased power requirements while walking. The investigation is aimed at determining the possibility of using transcutaneous spinal cord stimulation (TSCS) to influence the kinematics of walking in stroke patients with hemiparesis in the early and late recovery periods (1–12 months) after stroke. Continuous and phasic stimulation was used during motor training on a treadmill. For stimulation of spinal neuroprosthesis including a multichannel stimulator for TSCS (Cosyma, Russia) with sensors for determining the phases of walking was used. The biomechanical study of the walking function was carried out with the Steadys system (Neurosoft, Russia). The study involved 15 patients (ages from 33 to 79 years). We analyzed the parameters of stepping movements when walking on the floor without stimulation before and after training on a treadmill using TSCS. A comparative analysis of the kinematics of walking before and after training showed an increase in walking speed, the length of the step cycle, and an increase in the range of movements in the hip, knee, and ankle joints, in 40% patients the height of the paretic foot lift increased by 1–2 cm. The results show that the training with the use of TSCS can be considered as a rehabilitation method for correcting walking after a stroke.

Experimental Tests of Effect of Vertical Lifting Height, Horizontal Distance, and Weight Load Lifting Method on Muscle Activation Value Generated Using Electromyography

In industry, manual lifting activities certainly involve muscles and generate risks if done improperly. There are problems in the form of complaints from industrial workers on manual lifting activities that are carried out in a less ergonomic manner. This study aims to determine the effect of lifting factor variables on the resulting level of muscle activation. In this case, three factors are used, namely the lifting method factor, the horizontal distance factor, and the vertical distance factor, each of which has two factor levels to produce eight combinations of lifting factors. Randomization was carried out on research subjects totalling 10 people. Previous research that has been done manually is by calculating the pulse resulting from a lifting activity according to a specified frequency. In this study, monitoring of muscle activity was carried out automatically using an instrument called Electromyography (EMG) at three points of the hand muscles, namely the biceps brachii muscle, triceps brachii muscle, and brachioradialis muscle. The results of this study indicate the best combination based on the value of muscle activation on the biceps brachii muscle, triceps brachii muscle, and brachioradialis muscle which respectively include combination 2 (M1-H2-V1) with a significance value of 0.002, combination 6 (M2-H2 -V1) with a significance value of 0.000 and combination 2 (M1-H2-V1) with a significance value of 0.013. The resulting combination of the best lifting factors can be used as a reference and recommendations for the ideal lifting posture and conditions for workers in minimizing possible injuries

Effect of Probe Lifting Height in Jumping Mode AFM for Living Cell Imaging

Atomic force microscopy (AFM) is one of the effective methods for imaging the morphological and physical properties of living cells in a near-physiological environment. However, several problems caused by the adhesion of living cells and extension of the cell membranes seriously affect the image quality during living cell imaging, hindering the study of living cells. In this work, jumping mode AFM imaging was used to image living cells at varied probe lifting heights to meet image quality requirements, and image quality related to the probe lifting height is discussed in detail. The jumping mode was divided into three parts based on the varying heights of the lifted probe, namely near-contact mode, half-jumping mode, and full-jumping mode, and the causes of their imaging drawbacks were analyzed. At an appropriate lifting height, the probe can be completely free from the influence of cell adhesion and self-excited oscillation, thus avoiding the occurrence of “trail” phenomena and invalid points in the imaging of living cells and improving the image quality. Additionally, this work provides a new approach to calculating the lateral force through the adhesion of trace and retrace scanning at a low height, which is important for studying the extension characteristics of the cell membrane.
