Prediction and Simulation of Elliptical Drawing Based on DYNAFORM

摘要

Sheet metal stamping is an important method of plastic processing, which is one of the basic means of modern manufacturing industry. With the increasing demands of stamping quality, the production quality of stamping process optimization requirements are also rising. In this paper, finite element theory, the application of combination of dynamic display algorithm and static implicit algorithm, based on DYNAFORM platform, numerical simulation under different punch plate rounded, BHF, coefficient of friction, speed and other parameters of the stamping process have different influences on oval stretch formability. It offers good choice of selection of material, which reduces the costs of development of new products and shortens the manufacturing cycle of molds. It also provides some experience and help for oval deep drawing process in the future.
