摘　　要：利用有限元分析的方法,详细讨论了单缸柴油机曲轴的曲柄形状对曲轴最危险截面应力的影响,通过多种设计方案的计算比较,使曲柄圆角处的应力峰值下降11.25%。其中,一种设计方案已用于S1115X120单缸柴油机,并在大批生产中得到验证,证明该方案是行之有效的。By means of FEM, this paper discussed the shape of the crank angle has influenced upon the stress ot the most dangerous section of the crankshaft in single-cylinder diesel engine. Through the calculation and comparison of many designs, the peak stress of crankshaft fillets decreased by 11.25 present .Now one of the designs has been applied to S I 115X 120 single-cylinder diesel engine. And it is proved to be feasible in the manufacture.
