摘　　要：为了研究复合行星齿轮系振动信号频谱特征,以SD16再制造变速箱复合行星齿轮系为研究对象,建立系统动力学模型。通过系统转速特性、啮合频率以及啮合力计算分析,给出理想啮合力曲线。利用ADAMS仿真平台,对复合齿轮系动力学模型进行验证,并对双排行星架太阳轮与行星轮啮合力在系统绝对坐标系中x轴分量和y轴分量的时域和频域特性进行仿真分析,为再制造变速箱现场故障诊断频谱分析提供参考依据。仿真结果表明:啮合齿轮副啮合力时域波形与理想啮合力曲线基本一致,具有明显的波动性与周期性。在频谱分析中,齿轮副啮合频率的1倍频与2倍频为主要频率,存在明显的幅值调制现象。In order to study the vibration spectrum of compound planetary gear train, a SD16 remanufacturing gear box was considered, and the dynamic model was established. Through the calculation and analysis of the speed characteristic,meshing frequency and meshing force of the system, the ideal meshing curve was proposed. By using ADAMS platform,the model was verified and the time domain and frequency domain characteristics of meshing force between sun gear and planet gear of the double row planetary gear in absolute coordinate were simulated to provide reference for the fault diagnosis of remanufactured gear box. The simulation results show that the waveform of meshing force in time domain can match up with the ideal meshing curve, which has notable volatility and periodic property. In the frequency domain,the frequency multiplication of 1 and 2 of meshing frequency are the main frequency, which have explicit amplitude modulating characteristic.
