摘　　要：本文介绍了用二维有限元程序ＭＡＦＡＰ对斯太尔汽车转向节挤压工序变形过程和折叠缺陷的模拟分析，数值模拟结果与模拟实验完全吻合，并给出优化毛坯尺寸设计。该设计已用于实际锻件生产。文中还结合ＭＡＦＡＰ程序对塑性成形有限元基本理论进行了介绍。In this paper,we introduce the numerical simulation of the deformation process and fold defect of steering link in extrusion operation,by using a 2-D FE program MAFAP. The numerical results agress with that ones of simulation experiments accurately and an optimum blank dimension is gained, which has been used in production. In addition,basod on MAFAP, the primary theoretical charateristic of FEM of forging process is given.
