摘　　要：建立了平动回转式压缩机滑片的动力学模型,详细分析了运动、受力和磨损随主轴转角变化规律。利用ANSYS对滑片进行模态分析,确定其固有频率和各阶振型,通过比较临界转速和实际运行转速,证明了压缩机在运行过程中不会发生共振现象,为平动回转式压缩机的优化设计提供了依据。The dynamic model of sliding vane in translational rotary compressor was established, the variation characteristic with the rotation angle of its motion, forces and friction losses were studied. Modal analysis of sliding vane was carried out with ANSYS to dis- cuss the natural frequencies and vibration types, by comparing the critical speed and actual speed, the results proved that resonance would not happen. It provides foundation for the optimized design of translational rotary compressor.
