Abstract: Aiming at the problems that the subsequent simulation process can not inherit the previous step simulation results and each simulation processes are independent which do not match the actual problem during finite element modeling method for continuous simulation deep drawing process, a continuous positive and negative drawing forming process simulation and analysis based on ANSYS LS_DYNA was proposed based on the study of the finite continuous deep drawing process , parameter setting and treatment before and after processing. Using APDL statement controlled the analysis process and related parameters, the parameterization and generalizing were done. The key technical points of simulating continuous forming was summarized, which could be applied to finite element numerical simulation of continuous stamping. Numerical results show that the numerical analysis idea could achieve multiple consecutive stamping simulation analysis, whose results were more in line with the actual situation.
