摘　　要：在CAD系统中对高压低噪小流量离心泵泵体进行三维实体造型,应用ANSYS软件建立有限元模型并进行仿真计算,并对其进行了模态分析,得出了该类型转子的前10阶固有频率和振型,研究求解泵体的固有特性,为整个系统的动态响应计算和分析奠定基础.分析结果不但为泵的故障诊断、安全运行和振动控制提供了理论依据,还为其结构改进、优化设计提供了重要参数.A 3D entity modelling for a high-pressure low-noise small flow centrifugal pump body was carried out in a CAD system.The 3D FE model of the pump body is established,and the result of the vibration modal is analyzed and calculated with ANSYS.The former 10 ordered inherent frequencies and types of vibration of the pump body are obtained.The analysis result can provide theoretical basis for fault diagnosis,safety operation and vibration control,and the important parameters are useful for structural improvement and optimization design of the pump body.
