摘　　要：获取啮合力特性是开展行星轮系故障诊断的基础。运用SolidWorks与ADAMS建立健康状态和太阳轮点蚀故障状态下行星轮系的虚拟样机,合理设置仿真参数,对太阳轮与行星轮之间的啮合力进行仿真研究。结果表明:在太阳轮点蚀故障状态下,太阳轮与行星轮之间啮合力的时域波形具有周期性的冲击和调幅现象;啮合力的频域波形不仅出现了行星架的转频和太阳轮点蚀的故障特征频率,而且在行星轮系啮合频率及其倍频两侧出现了太阳轮点蚀故障特征频率的调制边频带;点蚀越严重,边带主频幅值比增大越明显。研究结果为行星轮系的早期故障诊断提供一定的理论参考。Obtaining the meshing force characteristics is the basis of fault diagnosis of a planetary gear system.The virtual proto⁃types of planetary gear system under the conditions of health and solar gear pitting failure were established by using SolidWorks and ADAMS.The simulation parameters were set reasonably,and the meshing force between solar gear and planetary gear was simulated.The results show that the time⁃domain waveform of the meshing force between the solar gear and planetary gear has periodic impact and amplitude modulation under the solar gear pitting failure condition.The frequency⁃domain waveform of the meshing force not only ap⁃pears the fault characteristic frequencies of the planetary frame rotation and the solar gear pitting,but also the modulation sideband of the solar gear pitting failure characteristic frequencies appears on both sides of the meshing frequency of the planetary gear system and its doubling frequency.More serious the pitting is,more obviously the amplitude ratio of sideband main frequency increases.The results provide a theoretical reference for the early fault diagnosis of planetary gear system.
