摘　　要：采用有限元方法对某型立式三缸双作用往复泵的曲轴进行应力分析,获得了曲轴整体应力应变状况,指出其运行的危险工况和最大应力点,并比较了2种结构设计方案的优劣。同时结合曲轴结构特性,对曲柄形状进行了优化设计,减轻了曲轴重量,便于加工,为同类往复泵曲轴的设计提供参考。Taking a type of vertical double-acting triplex reciprocating pump crankshaft as the research object,proceeded FEA to analyze the stress of the crankshaft, finding the most dangerous location at the most severe conditions and comparing with the two kinds of structure design. Then according to analysis ,combining with the structural characteristics of the crankshaft,the optimization design was carried out on the crank shape to save material and facilitate processing, providing a reference for similar design of reciprocating pump crankshaft.
