中文摘要：使用DEFORM-3D模拟软件对曲轴的成形过程进行了模拟分析。针对曲轴平衡块填充难的问题，通过优化终锻模具飞边槽结构，加入了阻力墙结构，改善了坯料的填充性，使其能够充满模具型腔，达到产品形状要求。并选取了成形速度和摩擦因子两个因素，分析了在不同参数下两种因子对锻模磨损的影响，与实际经验相吻合。
英文摘要：The crankshaft forming process was numerically simulated by DEFORM-3D simulation software. According to the question of crankshaft balance blocke being difficult to fill, through optimizing the flash cavity of the finished forging die, and joining resistance wall structure, the filling ability of billet was improved, the billet could fill mold cavity. The influence of the two factors (forming speed and friction factor) on wear was analyzed under different parameters, the simulation results were consistent with practical experience.
