Study on numerical simulation of the effect of process parameters on the thickness change in deep drawing

A reasonable FEM simulation model for numerical simulation of deep drawing process was proposed with respect to the characteristics of deep drawing.The thickness attenuation ratio under different forming condition were simulated by FEM and the influences of the key process parameters such as radius of die,friction coefficient,binder force,the gap between die and punch on the deep drawing process were analyzed.The experiment indicates that computer simulation can be helpful for studying the connection between deep drawing process and process parameters,and the results are beneficial of mould design and analysis of products quality.
