Abstract：

Based on the CAA technology of CATIA, the motion simulation and interference checking system for multistation automobile die was developed. Through the classification of die components, a templatedefined method was put forward, and the designer and the complicated subdefinition of motion subassembly was separated to realize a rapid definition of moving parts. Then, the system could achieve free removal, addition and reedit of moving parts by CATIA custom feature to store template data. Furthermore, the driving curve was obtained by analyzing the basic curve and parameters of moving parts, and a true and effective motion simulation could be achieved by driving curve. Compared with professional simulation software, the system realized the integration of the die design modification and simulation checking, and avoided repeated conversion of the model data. Thus, compared with the simulation module of CATIA, the system reduced many repeated operations in the simulation process, improved the design efficiency of multistation die, and shortened the development cycle.
