Thinning Rate

In this work, Numerical simulations based on finite element method have been carried out to study the effect of important process parameters on formability of AA5182 alloy sheets. The blank holder force between 0.5KN and 3KN and friction coefficient(μ) between 0.05 and 0.20, which resulted in successful drawing, was evaluated. Maximum percentage thinning has always been obtained at the conjunction of corner and bottom. The maximum thinning rate was nearly 20% for a maximum holder force of 3KN. Friction coefficient simulations are shown that as friction coefficient increasing, the thinning rate becomes larger and low friction coefficient is beneficial to the sheet forming.

In this paper, the flow rule of metal during the deep drawing of the non-symmetry workpieces was investigated by means of the numerical simulation of deep-drawing processes of square cup under bilateral constrained conditions. The numerical simulation was carried out by advanced analysis software Dynaform5.5. SUS304 stainless steel was used as the deforming materials. The influence of different friction coefficient and blank holder force on the drawing forming quality was analyzed. The results showed that the material flow in different areas has different trends with increase of friction coefficient and blank holder force.

Result Analysis

The effects of stamping process parameters (blank thickness, blank holder force, friction coefficient, die clearance) on the formability of an automobile reinforced plate were investigated. The process parameters are optimized based on the results of orthogonal testing. The optimal process parameters were obtained by simulation result analysis of variance. The accuracy of numerical simulation is verified by the experiment, which provides guidance for the actual production.

Numerical simulation of deep drawing of bottom of vacuum flask is made by means of finite element software ANSYS/LS-DYNA and the potential defect was analyzed. The influence of the blank holder force on deep drawing quality is discussed .The results show that the maximal value of stress and thickness appears in the round corners of die .The maximal increased thickness is sheet flange and the maximal thinning is the round corners of punch. The larger is the blank holder force, the less equal is the thickness and the poorer deep drawing quality.

Element Method

The plastic deformation behavior of axis symmetric aluminium 6061 cups was determined by analyzing the four important deep drawing process parameters, namely blank temperature, die edge radius, blank holder force and friction coefficient. Taguchi techniques along with finite element method (FEM) were used to determine the importance of process parameters. The Taguchi method was used to analyze the influence of each process parameter. From the deformation result and analysis of variance (ANOVA), it was determined that the temperature of the blank has a major influence on the deformation characteristic of aluminium 6061 sheets followed by die edge radius, coefficient of friction, and blank holder force. The optimum levels of the four factors in determining the deformed cup heights are found to be blank temperature of 450°C, die edge radius of 14 mm, coefficient of friction of 0.60 and blank holder force of 9 KN.

Suppression Effect

Springback is one of the main quality defects in the sheet forming. In this paper, numerical simulation is used to analyze the effects of blank holder force, friction coefficient, blank thickness, die corner radius and stroke on springback. The effect of blank holder force and blank thickness on springback is obvious. Springback decreases as the BHF and blank thickness increase. Increasing friction coefficient between tools and blank shows a good suppression effect on springback. Larger die corners increase the curvature of side wall and worsen the springback, but the springback of flange is reduced. The greater the stroke is, the larger the final springback will be.

Finite Element Numerical Simulation

The finite element numerical simulation for the formability of magnesium alloy AZ31B sheets with thickness of 0.8mm and diameter of 140mm has been proceeded to investigate the formability using the current finite element software. Under the condition with blank holder force of 8KN and deep drawing speed of 0.3mm/s at 200, the sytematic analysis and prediction of the thickness change and the forming rule for thesimulation process of the blank has been carried out. Under the same parameter, the drawing parts by deep drawing with a hydaulic machine were obtained and the thickness tested. It has been found that thickness change rules and the forming rules of the experimental results were in agreement with the numerical simulations.

The paper presents the results of research on the study of the elastic deformation of a flexible wheel from a double harmonic transmission, under the action of a cam wave generator. Knowing exactly how the flexible wheel is deformed is important in correctly establishing the geometric parameters of the wheels teeth, allowing a better understanding and appreciation of the specific conditions of harmonic gearings in the two stages of the transmission. The veracity of the results of this theoretical study on the calculation of elastic deformations and displacements of points located on the average fiber of the flexible wheel was subsequently verified and confirmed by numerical simulation of the flexible wheel, in the elastic field, using the finite element method from SolidWorks Simulation.
