摘　　要：以MG900/2215-GWD型采煤机截割部两级行星齿轮为研究对象,采用虚拟样机技术对其进行了动力学仿真研究。通过比较健康以及几种不同程度的断齿故障状态下的啮合力时域及频域曲线,对故障状态下两级行星齿轮系统的动态响应进行了分析。研究结果表明,故障情况下,啮合力边频带能量密集,且密集程度随着损坏程度增大而增加。该研究结果可以为两级行星齿轮故障诊断和检测提供理论依据。Taking two - stage planetary gear of the cutting part of MG900/2215 - GWD shearer as study object, the dynamics analysis simulation of it is carried out by using virtual prototype technology. By comparing the meshing force curves in time domain and frequency domain of the health and several broken tooth fault of va- rying degrees, the dynamic response of two - stage planetary gear system under fault condition is analyzed. It can be found that under fault condition, the mesh force side bands of energy become intensive, and the intensity increases with the extent of the damage increase. The research results can provide a theoretical basis for two - stage planetary gear fault diagnosis and testing.
