| 摘 要： | 简述了汽车发电机磁极几种典型成形工艺。基于Abaqus通用有限元软件,应用三维刚粘塑性有限元显式算法对磁极精锻成形过程进行了模拟分析,得出了变形中材料的流动状态和等效塑性应变分布规律。根据有限元模拟分析结果对磁极精锻成形工艺参数、模具结构进行了优化设计,并进行了磁极精锻成形工艺试验。试验验证了有限元模拟分析结果,并精锻成形出合格的汽车发电机磁极产品。

| Abstract: | Several typical forming processes of alternator pole were briefly explained. Based on general finite element software Abaqus/Exlicit, 3D rigid visco-plastic FEM was used to simulate the precision forging process, the laws of material flow and equivalent plastic strain distribution were revealed. Based on the results of FEM simulation, the process parameters and mould structure for precision alternator pole forging are optimized. Experiments of precision alternator pole forging have been made, the qualified alternator pole has been formed, and FEM simulation results are verified by experiments. |
