摘　　要：利用有限元软件DEFORM-3D对曲轴预锻和终锻成形后的模具进行了应力分析,得到了应力分布,阐述了容差值对模具应力的影响;进一步分析了模具的应力集中现象,以改善模具结构、提高模具的使用寿命。研究结果可为曲轴锻造成形模具的设计提供参考。Die stress analysis of the crankshaft after pre-forging and final forging was carried out by using finite element software DEFORM-3D.The stress distribution was obtained and the influence of error tolerance on the die stress was explained. The phenomenon of die stress concentration was further analyzed to improve the die structure and enhance the life of the die. The study results can provide a reference for the design of crankshaft forging die.
