960kW钻井泵曲轴有限元分析

摘要

通过三维软件Pro/e建立了钻井泵曲轴的三维模型,并对该三维模型进行了有限元建模.对曲轴进行了静态分析和模态分析,获得了曲轴的特征频率和相应的振型.计算结果为曲轴的结构优化和轻量化提供理论依据.%Throughing buit a three dimenional geomic modal , generated a finite element modal, loaded pressure. Ansys finite element analysis software was used to implement the calculation of static strength of the crankshaft and dynamic analysis . Thus obtaining characteristic frequency and the corresponding vibration mode. The results of the analysis provide theoretical basis for the design improvement and weight lighting of the cranksharft.
