介绍了采用基于动态显式算法的有限元分析软件包eta/DY-NAFORM对典型的汽车覆盖件轿车车门内板冲压成形进行计算机仿真的全过程。论述了覆盖件冲压零件计算机仿真必须注意到的问题,并探讨了其中的关键技术。
This paper introduces the whole process of computer simulation of the stamping of the inner panel of a typical car cover car door with eta / DY-NAFORM, a finite element analysis package based on the dynamic explicit algorithm. The problems that must be noticed in computer simulation of stamping parts are discussed, and the key technologies are discussed.
