中文摘要	Taking the forming processes of half-shaft bushing, wayshaft, and starter socket as examples and aiming at the typical problems in extrusion of automotive parts, some defects such as folding, underfilling, and cracking were numerically simulated and predicted in this paper with rigid-plastic FEM, rigid-viscoplastic FEM, and thermo-mechanically coupled methods by means of DEFORM3D. The distribution laws for the stress, strain, velocity, and temperature in the forming processes were analysed. The reasons for the defect generation were discussed, and some optimum measures for these processes were put forward. The results agree well with the experiments. Several proposals for prediction and simulation of extrusion defects of these automotive parts are put forward. It was instructional to apply FEM to the quality control of the extrusion.
