立式循环泵转子系统动态特性分析

摘要

运用ANSYS软件对换热站立式循环泵转子进行有限元模态分析。在Solidworks软件中建立泵转子的三维实体模型，导入ANSYS有限元软件进行模态分析，采用LMS test. lab振动噪声测试系统进行数据采集和分析后处理。研究了支撑方式和轴承刚度对泵转子系统固有频率的影响规律，为泵的结构优化提供理论基础，为转子结构的动态响应分析提供理论依据。%This paper uses software ANSYS to analyze the finite element model of the rotor of the vertical circulating pump and establishes its threedimensional solid model in software Solidworks. The LMS test.lab noise and vibration test system is used for data col ection and processing.The influerce of the supporting type and bearing stiffness on the rotor natural frequency is discussed.The theoretic basis is provided for the structural optimization and the dynamic response analysis of the rotor.
