摘　　要：对一个轿车发动机的曲轴进行了符合实际情况的三维建模 ,校核了曲轴在交变载荷下的疲劳强度 ,并通过曲轴的疲劳试验对分析和计算结果进行了验证。对忽略惯性力、忽略相邻曲拐影响、忽略扭矩的简化模型分别进行了计算 ,得出了不同建模方法对计算结果精度的影响。对曲轴圆角形状优化。This paper processed three dimensional modeling of motor crankshaft,which was corresponding to practice condition.On this foundation,the fatigue security factor of crankshaft was verified then were validated through fatigue experiments.The precisions of some simple methods were compared respectively.Optimum design of fillets,the stress distributions of round corner and the design of deep rolling craft of crankshaft were discussed.
