指出钣料成形过程中采用曲面压料面时， 压边圈夹紧过程动力显式有限元分析存在惯性效应问题。提出 “虚拟补实压边圈”方法克服惯性作用， 高效实现曲面压边圈夹紧过程的动力显式有限元模拟， 拓展动力显式有限元方法在钣料成形数值模拟中的应用领域， 对于连续快速地模拟曲面压边和拉延等多阶段钣料成形过程意义重大。
It is pointed out that the dynamic explicit finite element analysis of blank holder during the forming process of sheet metal forming has the problem of inertial effect. The method of “virtual face blanker” is presented to overcome the inertia and to realize the dynamic explicit finite element simulation of the face blank holder clamping process efficiently. The application field of dynamic explicit finite element method in numerical simulation of sheet metal forming is expanded. Continuous and rapid simulation of surface crimping and drawing and other multi-stage sheet metal forming process is of great significance.
