Aluminum/steel rolled composite finite element secondary development simulation and experimental study

Given the significant difference in the properties of the two metals, the rolled composite has a severe problem of uncoordinated deformation and low bond strength. The effect of the same diameter and different diameters of the rolls and single roll drive on the composite plate’s coordinated deformation and bond strength is investigated. Simulation modeling employs finite element (FE) secondary development, and the plate warpage mechanism is analyzed by combining synchronous and asynchronous rolling experiments. The aluminum side is subjected to compressive stresses in the rolling direction during the rolling process. The steel side is subjected to tensile stresses in the rolling direction. The roll diameter in contact with the aluminum plate is reduced, the rolling pressure is distributed more evenly along the vertical plate section direction, improving deformation coordination. The side of the roll that touches the aluminum is driven, and the bimetal starts to bond closer to the exit of the roll. The frictional stresses and bending moments between the bimetallic interface are smaller, resulting in better deformation coordination and higher bond strength.

Quantitative analysis and validation using computational approach for hollow spherical roller bearing 22212E

A bearing is a part of the machine that lowers friction between moving parts by limiting relative motion to only the desired motion. Bearing debility is affected by a several factors, also the roller–raceway interfaces are the most significantly stressed areas in a bearing, minimizing the Hertz contact stresses there has been a main objective. The analytical and finite element approaches have been used to evaluate the deformation, contact stress and contact pressure of spherical roller bearings 22212E. It has been observed that the acquired results employing the theoretical and FE Analysis methods have quite a 9 percent variation. Based on results, confirming the FEA for solid spherical bearing with a theoretical approach using the same operating parameters. Furthermore, the finite element approach has been employed to analyse how the hollow spherical rolling element enhanced the bearing performance. In ANSYS, multiple hollowness percentages ranging from 0% to 90% of the external diameter of the spherical roller were analysed in order to determine the optimal hollowness for bearing service life. It has been discovered that bearings with a hollowness of roughly 62 percent have the lowest contact stress, which extends the bearing's fatigue life.

Single- and multi-objective optimization of internal gear flowforming process based on increasing tooth height and reducing force and built-up edge

Flowforming is an incremental metal forming process in which deformation occurs gradually between the roller and mandrel. This process has been widely used for manufacturing of high-precision tubular parts and seamless tubes. Internal gear flowforming process is a new method for manufacturing an internal gear that requires no additional machining process. In this study, the design of experiment method and regression analysis were used to obtain tooth height, force, and built-up edge as functions of the effective parameters, including feed rate, roller diameter, attack angle, and thickness reduction percentage. Next, the simulated annealing and genetic algorithm were used for, respectively, single- and multi-objective optimization of the obtained functions. The goal of optimization was to reduce the force and built-up edge and increase the tooth height. In single-objective optimization, the maximum tooth height was 0.576 mm, the minimum force was 1606.63 N, and the minimum built-up edge was 0.448 mm. In multi-objective optimization, an optimal set of tooth height, force, and built-up edge (Pareto front) is obtained.

Cylindrical interfaces repair technique using electric resistance welding of metal powder materials

The study aims to increase the manufacturability of cylindrical interfaces repair by restoring the outside surface geometry using electric resistance powdered welding. The paper presents the technique of coating a worn outside cylinder surface using metal powders and mesh by giving the results of the quality indicators study. The research allowed identifying optimal parameters for the metal powder supply depending on the metal mesh size and the powder's technological properties. Theoretical studies have been undertaken to substantiate the technological process parameters. The nomographic chart developed to determine the angle of powder supply to the electric resistance welding zone allows predicting the coating thickness and varying within 0.3 … 1.5 mm. The powder brand, the diameter of the electrode roller, part and mesh are considered when developing the chart. Due to the triaxial compression under the electrode rollers' force and the mesh deformation, the powder layer experiences additional compaction and is practically sintered to a compact state. The coating obtained under optimal conditions has a porosity of 2 … 6%. Laboratory and operational tests allowed justifying the applicability of coatings in interfaces operating using lubrication and experiencing moderate loads. The electric resistance welding provides high anti-friction properties of resulting metal coatings (1.9 times higher than hardened steel 45, and HD80 (high duty) cast iron by 1.6 times). The developed technology makes it possible to restore cylinder parts worn to 1 mm with wear resistance higher than that of new parts such as the support surfaces of drive shafts, screw rotors, mould guides, etc.

Plastic Behavior and Microstructure Heterogeneity of an AA6063-T6 Aluminum Alloy Processed by Symmetric and Asymmetric Rolling

Rolling is one of the most employed industrial processes which can be used at multiple manufacturing stages, allowing different geometries such as plates, rods, profiles, billets, slabs, tubes, and seamless tubes to be obtained. However, rolled products develop anisotropy due to the preferential orientation of crystals in the rolling direction. Thus, some process configurations and different processing parameters (e.g., thickness reduction per rolling pass, deformation routes, roll diameters, and strain rate) have been proposed to deal with the desired anisotropy. In this context, this investigation evaluates and compares the effect of symmetrical and asymmetrical rolling on an aluminum alloy sheet deformed until a 38% thickness reduction using multiple rolling passes. The asymmetrical process displayed larger texture and microstructure gradients across the sheet thickness than the symmetrical one, manifested as more grain refinement and more intense shear texture components close to sheet surfaces. In terms of plastic anisotropy, the visco-plastic self-consistent model predicted higher average anisotropy for the symmetric rolling than the asymmetric process due to a strong combination of recrystallization and deformation texture components. Conversely, the asymmetric process showed lower planar anisotropy values due to the increase in the fraction of shear and deformation texture components near the sheet surfaces, producing a less intense overall texture than the symmetric rolling. The additional shear strain component was mainly responsible for the material strengthening and texture weakening after the asymmetrical rolling process. In addition, the shear strain produced grain refinement, decreased misorientation, and higher dislocation densities than the as-received and symmetrically rolled materials. After asymmetrical rolling, the microstructure and texture showed heterogeneous profiles across the sheet thickness. This gave rise to a heterogeneous grain size refinement, decreased misorientation close to sheet edges, and plastic gradients.

Rolling characteristics of multi-filamentary Bi-2223/AgAu tapes and roller diameter′s effect on transport properties

37-filamentary Bi-2223/ AgAu tapes were fabricated by powder in tube technique. The round wire (φ1.51 mm) were rolled to 0.30 mm tapes by 150 mm, 250 mm and 300 mm roller through flat rolling, respectively. A fundamental understanding of filaments deformation and roll diameter′s effect on critical current properties were systematically investigated. By analyzing the stress distribution on cross section during rolling, it can be understood that the deformation of the filaments at different positions during the rolling of multi-filamentary Bi-2223/AgAu tape is inhomogeneous. According to the deformation extent of filaments, the cross section of the tape can be divided into three areas, namely easy deformation zone, difficult deformation zone and free deformation zone. The average filament width in the free deformation zone is only 65.1 % of the filament width in the easy deformation zone. It can be noticed that the Jc values increase monotonously with increasing roller diameter. Due to more sufficiently deformed filament and flat interfaces, Jc reached the maximum value of 15.7 kA/cm2 on the 300 mm roller sample.

Analysis of electric current supply circuits to rolls during electroplastic rolling of tungsten microstrips

One of the important problems in the design and operation of the electroplastic deformation mill is the reliability and uniformity of the supply of powerful electric current to the deformation zone. The high density of the electric current and the uneven distribution of it leads to a different manifestation of the effect of electroplasticity along the width of the strip, an uneven temperature field, and as a result, to a decrease in the quality of the finished product. To evaluate various current supply circuits, a discrete model is proposed, in which the work rolls and the rolled strip are presented as combinations of lumped resistances. The model was used when considering four main circuits for supplying electric current to the rolls of the electroplastic deformation strip mill: straight one-sided, diagonal onesided, direct two-sided, diagonal two-sided. For all circuits, formulas were obtained for calculating the electric currents flowing in the center of the strip and along its edges. The dependences obtained using the developed model show that the greatest non-uniform distribution of electric current across the width of the rolled strip occurs with a direct one-sided current supply. At the same time, its undoubted advantage over other options is a simpler design. Diagonal single-sided and both variants of double-sided current supply (according to this model) give the same results. The main disadvantage of these options is the need to supply electric current from both sides of the rolling mill. Regardless of the selected current supply option, it is necessary to minimize the ratio of the electrical resistances of the roll materials and the deformed material. In particular, this can be achieved by increasing the diameter of the work roll, as well as by choosing a roll material with high electrical conductivity. The model for supplying electric current to the work rolls and recommendations for reducing the uneven distribution of current across the width of the strip are used in the design of electroplastic deformation mills.

Models and Patterns of Bamboo Fiber Splitting under Bending Load

In this study, we investigated the macro and micro mechanisms of bamboo bending failure, and a new method to unfasten bamboo fiber by continuous bends and large deformations is put forward. The method could effectively maintain the fiber structure integrity without damage. Bamboo strip with load deformation was considered a continuous beam, and the bending moment and the matrix cracking of the bamboo were analyzed on the basis of elastically plastic theory. The mechanical model to unfasten the bamboo fiber under continuous bending was established using the principle of virtual work, while the loading conditions were obtained. The arithmetic expressions for the loading roller diameter and distance, as the main parameters, were obtained analyzing bamboo splitting under different strain conditions. The fiber splitting test further verifies our method and models, which provide a new idea and way for bamboo fiber splitting by mechanical method.

Effect of process parameters on performance of grooved hot rolling of SAE 4340 steel bars

ABSTRACT SAE 4340 alloy steel is used in structural parts, forging industry, gears and shafts used for power transmission and landing gears of aircraft. Basic production process of the metal bar involves heating the billet in reheating furnace up to 1200°C–1210°C followed by passing it through a pair of grooved rolls in a rolling mill. The roll separating force, driving torque and end crop length are the important issues to be controlled for quality production, maximization of yield, minimization of rolled bar process scrap, safety of mill and reduction in energy consumption. These response parameters depend on several process parameters – rolling speed, billet temperature, reduction ratio (strain), billet size (cross-section area), roll diameter, etc. This paper presents a study on the effect of process parameters on these response parameters during grooved rolling of SAE 4340 steel. Simulation of the rolling process has been attempted using FORGE® Nxt 1.1. The simulated results so obtained have been validated through experimental results obtained in a rolling mill, following statistical tests. Regression models showing relationship between the process parameters and the response parameters have been developed. Significant model-terms have been obtained using analysis of variance.

Experimental research results on the erosion study of the temporary irrigating canal dam with pouring water and the establishment of the size of the dam compactor’s operating body

Research work has been carried out for several years in order to mechanize the technological process of dams' compaction and the development of a dam compactor. As a result of the experiments, the design of the dam compactor and the types of operating bodies were selected, the main optimal dimensions of the dam compactor were determined and mathematically analyzed. It was revealed that the main parameters of the dam compactor affecting the compaction process of temporary irrigating canal dams are cone roller diameter, length and width of the plate compactor, and the angle of dam nip. These parameters have been substantiated by theoretical and experimental studies. The optimal values of these parameters were determined by the mathematical planning of the experiment; below are the limits, as well as the variation levels of these factors. Based on the results obtained, an improved dam compactor was manufactured, and experimental studies were conducted in the field. At the same time, an increase in productivity relative to existing methods has been achieved and the compaction index has been brought to the required value. The mathematical model of the research object is the response function of an equation linking optimization parameters with controlled factors. The hypothesis of variance uniformity in the same non-repeated experiments was tested using the Cochran's test, and the significance of the regression coefficients was determined by the Student's criterion. The adequacy of the process model was checked by the Fisher criterion. After processing the experimental data and evaluating the coefficients' significance, regression equations describing the dam compaction process by the dam height and the compaction degree of the temporary irrigating canal dam were obtained. The main dimensions of compacting operating bodies of the dam compactor were selected.

Effect of process parameters on roll separating force, driving torque and end crop length during grooved hot rolling of SAE 1020 steel

The rolled SAE 1020 steel bars are widely used for production of gears, spindles, camshafts, axles, fasteners, and gudgeon pins etc. Steel industries are striving for productivity and better yield of hot rolled bar products. The roll separating force (RSF), driving torque (DT) and end crop length (ECL) are the important issues to be controlled for quality production, maximization of yield, minimization of rolled bar process scrap, safety of mill and reduction in energy consumption, etc. These response parameters depend on several process parameters – rolling speed, billet temperature, reduction ratio (strain), billet size (cross section area), roll diameter, etc. This paper presents a study on the effect of process parameters on these response parameters during rolling of SAE 1020 steel. Simulation of the rolling process has been attempted using FORGE® Nxt 1.1. The simulated results so obtained have been validated through experimental results obtained in a rolling mill, following statistical tests. Regression models showing relationship between the process parameters and the response parameters have been developed. Significant model-terms have been obtained using ANOVA.

Magnetorheological finishing of aluminium cylindrical roller for enhanced performance of printing operation

Aluminium is the most versatile engineering material for various industries, such as transport, machinery, metallurgy and printing. The aluminium cylindrical roller plays a significant role in the printing machine. In order to evenly distribute the pressure and for accurate tolerances roller needs to be perfect and uniformly finished. Owing to their ductility and lesser hardness, it is difficult to achieve uniform and fine finishing by conventional finishing methods. The rotary magnetorheological (MR) method is established to satisfy this requirement. The MR polishing fluid composition is initially analysed in order to obtain a fine finish. The central composite design was employed to optimize the finishing parameters. The batch gradient descent algorithm is used to validate the RSM optimization of process parameters. Batch gradient descent gives the mathematical model which validates the RSM mathematical model. The scan electron microscopy, reflectivity test and surface roughness profile check were carried out to track the surface texture and the cylindrical aluminium roller's ruggedness. The standard deviation test is performed to measure the uniformity of the finished surface and demonstrate that the uniformity of the finished surface which is increased. Geometric measurements are tested by the way of the surface waviness measurement. The results of earlier process parameters and with addition of reciprocation of work-part is compared and experimentation performed on 120 mm long and 25 mm diameter of the aluminium cylindrical roller with 30 mm length for each trial.

Investigation of thermal state of long mandrels on three-roll rolling mill

A technique was developed for the numerical analysis of the thermal state of long mandrels of a three-roll rolling mill using modern computer simulation software. The initial and boundary conditions were determined taking into account the peculiarities of rolling in a three-roll screw rolling mill on a long mandrel. The authors carried out a qualitative assessment of the thermal state of a long mandrel by means of visualized representation and established its significant inhomogeneity. Influence of the rolling temperature and diameter of the long mandrel were revealed. Small diameter mandrels are heated to higher temperatures (577 °C) with a significantly lower gradient between the axial zone and the surface. An increase in the mandrel diameter to 154 mm lowers the temperature of the outer surface to 530 °C and increases temperature gradient in the near-surface layers up to 18 °C/mm. So the temperature in the near-surface layers for a mandrel of 154 mm at a distance of 10 – 15 mm from the surface decreases from 530 °C to 315 °C. Features of the temperature field in the cross section were established taking into account thermal interaction of the sleeve with the mandrel in the zone of contact with hot metal and in gaps between the rolls. Temperature of the near-surface layers in the contact zone is 30 °C higher than in the gaps. Dependences of temperature of the cross-section characteristic points on the rolling time were determined, it has been established that in the first two seconds there is an intense growth according to the parabolic, and then according to the linear laws. Temperature of the central layers with a radius of 50 mm increases with a much lower intensity, by about 100 °С during the entire period of rolling, while during the same time, the near-surface layers are heated by 300 – 400 °С.

2D Magnetic Actuation and Localization of a Surface Milli-Roller in Low Reynolds Numbers

Magnetic actuation of minimally invasive medical tetherless devices holds great promise in several biomedical applications. However, there are still several challenges in noninvasive localization, both in terms of sensing detectable signals of these devices and estimating their states. In this work, a magnetic milli-roller is actuated in a viscous fluid under the influence of a rotating magnetic field. A Lyapunov-based nonlinear state observer is designed and implemented to estimate the position of the roller using a 2D array of Hall-effect sensors. We show that the local stability of the state observer yields convergence to one of the local equilibria, for pre-defined levels of sensor noise, initial conditions, and modeling errors. Performance is quantified using redundant measurements of the fields and we investigate the influence of the number of magnetic field measurements on the observability of the system. Open-loop actuation and state estimation are demonstrated and experimental results show that the localization of a 5 mm diameter roller along sinusoidal, circular and square trajectories achieve a steady-state mean absolute position error of <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$2.3 \,\mathrm{m}\mathrm{m}$</tex-math></inline-formula> , <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$1.67 \,\mathrm{m}\mathrm{m}$</tex-math></inline-formula> and <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$1.73 \,\mathrm{m}\mathrm{m}$</tex-math></inline-formula> , respectively.

An innovative constraining ring rolling process for manufacturing conical rings with thin sterna and high ribs

Conical rings with thin sterna and high ribs (CRTSHR) are key bearing-load parts of aerospace equipment, which are required to be manufactured with high performance and efficiency. Traditional ring rolling is the most preferred method for manufacturing high-performance ring parts, but it can hardly achieve the forming of CRTSHR due to the extreme geometry of CRTSHR. To solve this difficulty, an innovative constraining ring rolling process (CRR) is proposed in this paper to manufacture CRTSHR. To evaluate the proposed CRR and reveal its deformation behaviors, a thermomechanical coupled FE model for CRR of CRTSHR is established. Then, the experiment for CRR of CRTSHR is performed on a modified ring rolling machine, which proves that CRR of CRTSHR is feasible and the established FE model is reliable. Based on the reliable FE model, the metal flow mode in deformed CRTSHR is analyzed, and the deformation characteristics such as the stress state, strain distribution and the evolution of power parameters in CRR of CRTSHR are revealed. Finally, the influences of key parameters such as the friction factor between ring and molds, the diameter of idle roll and the feed velocity of idle roll on CRR of CRTSHR are investigated by FE simulation.

Analysis of the influence of roll size change on electromagnetic heat conversion capacity and roll profile control characteristics in the RPECT

RPECT is proposed to solve the problem of flatness control for cold-rolled strip processing. As one of the core components of this technology, the roll size is the key factor that affects the capability of the heat conversion and the roll profile control. So an electromagnetic thermal mechanical coupled axisymmetric model under the same electromagnetic rod structure and size is established to research this problem. After research, the results show that, with the roll diameter increasing, the induction heating efficiency changes a little, the average contact-stress increases, the roll crown decreases. Moreover, the control ability of roll surface cooling on roll temperature, roll crown and roll profile decreases. And the control effect on roll temperature, roll crown and roll profile weakens with the increase of roll surface cooling intensity. Therefore, when the electromagnetic rod structure is determined, the principle to be followed in the design of the roll used in the RPECT should be as follows: on the premise of meeting the strength and stiffness requirements of roll, the roller diameter should be small as much as possible.

Process Optimization for Manufacturing Functional Nanosurfaces by Roll-to-Roll Nanoimprint Lithography.

Roll-to-roll nanoimprint lithography (RTR-NIL) is a low-cost and continuous fabrication process for large-area functional films. However, the partial ultraviolet (UV) resin filling obstructs the ongoing production process. This study incorporates UV resin filling process into the nanopillars and nanopores by using RTR-NIL. A multiphase numerical model with a sliding mesh method is proposed in this study to show the actual phenomena of imprint mold rotation and feeding of UV resin on the polyethylene terephthalate (PET) substrate. The implementation of UV resin filling under environmental conditions was performed by utilizing the open-channel (OC) boundary conditions. The numerical model was solved by using the explicit volume of fluid (VOF) scheme to compute the filling on each node of the computational domain. The effects of different processing parameters were investigated through the proposed numerical model such as imprinting speed (IS), contact angles (CAs), viscosity, initial thickness of the PET, and supporting roll diameter. A good agreement was found between numerical simulations and experimental results. The proposed numerical model gives better insights of the filling process for the mass production of functional surfaces with nanopillars and nanopores patterns for different applications on an industrial scale.

Effect of roller diameter on the production rate in hot rolling process: Mathematical modeling and experimentation approach

Metal forming techniques are critical in the industrial sector. Metal forming procedures are used to create components with cross-sections such as conical, elliptical, cylindrical, oval, etc. As mentioned earlier, one of the procedures for forming the shapes is plate bending. The functioning of a plate rolling mill is related to various loading restrictions, while metals are bit with the lateral rollers of a reversed roller stand. Hot rolling is a vital phase in the manufacture and fabrication of steel sheets, resulting in a product with a high degree of flexibility. The paper justifies the experimental model, which verifies the experimental result using a mathematical model for the hot rolling process production rate. The mathematical model was developed using the Buckingham Pi (π) methodology and the dimensional analysis method. In addition, the influence of roller diameter on production rate was calculated at a diameter of 225 mm, 285 mm and 345 mm. The maximum production rate of 46.2 tons, 49.5 tons and 53.0 tons was observed at a roller diameter of 225 mm, 285 mm and 345 mm respectively. The percentage error between experimental and mathematical readings varies from 4.1 to 10.0%, 3.7 to 8.6% and 2.3 to 8.2% at roller diameter of 225 mm, 285 mm and 345 mm respectively. The experimental results are closely related to mathematical a modeling value, which further verifies the developed mathematical model using the Buckingham Pi (π) approach.

Finite element simulation of liquid nitrogen temperature rolling of marine grade aluminium alloy 5754

Now days, numerical approaches are becoming an efficient practical tool for the analysis of elastoplastic behavior of various engineering materials. Present study elaborates about the numerical investigation of liquid nitrogen temperature (LNT) plate rolling operation of marine grade aluminium alloy 5754 (AA 5754) by finite element method. To serve this purpose, commercially available ANSYS software package has been utilized to perform LNT-rolling simulation. In literature, it is well documented that LNT-rolling immensely increases mechanical strength through grain refinement technique. During rolling at liquid nitrogen temperature, the dynamic recovery process is inhibited which leads in accumulation of high rate of dislocation defects. Consequently, with due rolling these accumulated dislocations attributed towards formation of ultrafine grain (UFG) structure. The aim of this work is to formulate an efficient method to numerically investigate the deformation characteristics of AA 5754 during LNT-rolling. Geometrical and experimental parameters like roller diameters, dimensions of flat plate, roller speed, friction coefficient etc. are incorporated in the preprocessor module of ANSYS software. An optimized meshed domain is selected for simulation of 40% thickness reduction of AA 5754. The temperature effect and corresponding stress distribution in the flat plate of AA 5754 is well captured and comparative analysis with the experimental practices has been successfully carried out. Numerical results obtained in the form of uniform thickness reduction, elastoplastic stress and strain contour plots, pressure force exerted by roller etc. are in good agreement with the experimental rolling operation.
