摘　　要：使用有限元法对叶轮进行结构静力学分析。首先在UG中建立叶轮的三维实体模型,然后由FLUENT软件仿真得出泵腔内的油压分布,再在ANSYS中以solid187单元类型划分网格,通过对叶轮的结构静力学分析,可以清楚地显示其应力分布,找出应力集中点,验证其可靠性,并为进一步的模态分析和瞬态分析打下基础,为泵的结构优化提供了数据支持。In this article,the static structure of an impeller is analyzed using finite element method.Firstly,UG is used to draw a solid model of the impeller.Then FLUENT is employed to simulate the distribution of oil pressure in the pump and element type solid187 is used to mesh the impeller in software ANSYS.By performing a structural static analysis,the stress distribution within the impeller can be clearly observed.As a result,stress concentration points will be easily found,and the reliability of the impeller is verified.The result attained from the analysis lays a foundation for further mode analysis and transient analysis of the impeller,and provides the necessary data for structure optimization of the impeller.
