摘　　要：为避免双作用叶片泵在高速运转时发生共振破坏,现以叶片泵的高速转子结构为研究对象,利用三维建模软件Pro/E建立了高速转子结构的三维模型,再利用ANSYS软件,对高速转子结构进行预应力模态分析,得出转子结构的应力分布情况以及各阶固有频率,通过改变转子轴的尺寸,使其固有频率避开叶片泵噪音频率范围,避免共振。In order to avoid resonance damage of double-acting vane pump in high-speed operation,this paper takes the high-speed rotor structure of vane pump as the research object,establishes the three-dimensional model of high-speed rotor structure by using three-dimensional modeling software Pro/E,and then uses ANSYS software to carry out the pre-stressed modal analysis of the highspeed rotor structure,obtains the stress distribution and the natural frequencies of the rotor structure.By changing the size of the rotor shaft,its natural frequency avoids the noise frequency range of the vane pump and avoids resonance.
