To improve thick plate Multi-point forming process pre-process efficient,developing a thick plate Multi-point forming process simulation assistance program based on python programming and ANSA API.This program includes two modules which are model preparing and model creating.Model preparing module uses to locate punches which consist of target surface quickly and keep the punches initially contact with the blank.Model creating module uses to define boundaries and simulation parameters.A series of sphere parts with different curvature radius are created under the help of the Multi-point forming process simulation assistance program,stamp and spring-back are also simulated.The results show that it is able to create the Multi-point forming process simulation model quickly under the same software environment,which molds surface is complex.Simulation results of spring-back is agree with the test results.The bigger of the curvature radius,the worse of the results.Multi-point forming process simulation assistance program enhances the model preparing efficiency and shortens the simulation period.
