Research on Finite Element Simulation for Sheet Metal Forming Processing Based on Marc Software

It is important in sheet metal forming to eliminate the defects of products and improve the forming quality by formulating reasonable forming process and parameters of the die.This paper discusses the method of analyzing the thickness deformation of sheet metal,forecasting shortcoming of forming,and finding out the factor to influence forming quality by the way of the numerical value in sheet metal forming.An instance is utilized to explain the procedure.This paper simulates the forming procedure of a typical drawing-cylindrical drawn workpiece via the FES software msc.marc.The thickness distribution of the simulation and experiment shows good agreement.
