摘　　要：曲轴是内燃机的重要零部件,它对内燃机的动态特性有很大的影响。对R6105型柴油机的曲轴使用Solid Works 2007建立简化模型,并使用ANSYS有限元分析软件,对曲轴进行模态分析,查看其固有频率并分析计算了曲轴的前8阶非零振型,为曲轴的优化设计和动力学分析提供依据。Being one of the key parts in internal combustion engine,crankshaft can influence the dynamic characteristics of the system greatly.By using the simplified model of the crankshaft of R6105 diesel engine built by SolidWorks2007 software, the modal parameters were calculated with finite element software. And its inherent frequency characteristics were investigated by using finite element method. And we also analyze and calculate the foregoing eight non-zero model shape of the crankshaft These can provide a basis for the optimization design of crankshaft and its dynamics analysis.
