Research and application of parallel computation for the punching simulation of large auto cover parts

Because of the limitation of FEM,CAE softwares still have some defects in application,which make it very difficult for them to settle the problem between computational accuracy and speed.The key technologies of dynamic explicit FEM parallel simulation system for punching process were introduced in this paper.Through the application of the parallel punching simulation system in large auto cover parts forming analysis,the important value in practical application of the system has been proved.This system is very important for the progress of sheet forming technology.
