摘　　要：对直线共轭内啮合齿轮泵泵轴进行动态分析。利用有限元分析软件ANSYS Workbench,通过模态分析计算出泵轴固有频率和临界转速;同时,对其进行谐响应分析,得到交变载荷作用下泵轴产生共振的激振力频率,为防止泵轴发生共振提供可靠的理论依据。We finished the dynamic analysis on the shaft of a straight conjugate internal gear pump by using the finite element analysis software ANSYS Workbench,calculated the natural frequencies and the critical speed of the shaft by the modal analysis.The resonance frequency which occurs under the cyclic loading is obtained by the harmonic analysis.This study provides a reliable theoretical basis for preventing resonance of the spindle.
