摘　　要：利用有限元分析法对某V型发动机曲轴的两种结构方案进行数值模拟,获得曲轴结构的应力大小以及分布情况,考察其结构方案的强度,为发动机的曲轴结构设计提供参考依据。Using the finite element analysis,the two structural schemes of the crankshaft for a V engine was simulated.The size and the distribution of the structural stress are obtained.The strength of the structural schemes was studied,to provide the design basis for the crankshaft of the engine.

关 键 词：曲轴 结构强度 有限元分析 应力
