Research on Numerical Simulation for Multi-position Progressive Stamping of Car Oil Pan

Abstract

This paper realizes the finite element simulation technology of "die surface drive" based on AutoForm software which is combined with CATIA software. Take the case of deep drawing of car oil pan, it determines the forming process through the research of the three-dimensional modeling diagram firstly. Then the parts material are customized and the finite element model of the key working procedure in the multi step stamping process is established by AutoForm software. After that, the finite element model is simulated and calculated. Simulation results for drawing, shaping, trimming and flanging process are obtained which can meet the design requirements. Finally, the validity of the numerical simulation of the multi station continuous stamping process of the car oil chassis is verified by the testing data of the workpiece and the 3D coordinate measuring instrument.
