摘要
利用高级非线性软件MSC.Marc,采用弹塑性热机耦合分析对行星套冷挤压过程进行了模拟,得出了塑性成形的流动规律和模具的应力分布,比较了不同建模方法对模拟结果的影响,比较全面地阐述了冷挤压塑性成形的有限元仿真技术。研究结果对冷挤压成形的有限元仿真以及塑性成形工艺控制和提高模具寿命具有指导意义。
The course of cold extrusion of the starlike inner race was simulated by the 3-D elasto -plastic coupled thermal-mechanical FEA method, using the advanced nonlinear FEA analysis software. MSC. Marc; then the flowing rule during the course and the stress distribution on the mould were obtained, comparison was made in several available methods,and the FEA method of cold extrusion was described in detail. This result plays a guidline role on the simulation of the cold extrusion, controlling of the technical parameter and improvement on the life of the mold.
