摘　　要：针对衬套零件的特点,分析了成形工艺及挤压前处理,应用DEFORM-3D软件建立有限元模型进行仿真模拟,定点追踪了关键部位在成形过程中的应力、应变、流速等变化情况,并依此为依据设计出双层组合式预应力挤压模,为实际生产提供了有价值的参考。According to the characteristics of bush parts,the forming technology and pretreatment of extrusion was analyzed, the finite element models were set and simulated by DEFORM-3D software. Stress, strain and the velocity change etc. of key parts in the forming process was fixed-point tracking, a double combined-type prestressed extrusion die was designed based on the simulation analysis, provides valuable reference to practical production.
