行星齿轮箱扭振信号不受时变传输路径造成的额外调幅影响，并且比平移信号具有更简单的频率结构。齿轮故障导致扭转共振振动的调制并通过调制特征表现出来。本文利用这些优点进行行星齿轮箱故障诊断。将齿轮故障引起的共振区扭转振动建模为调幅和调频（AM-FM）过程，推导了傅里叶谱的显式方程，并总结了边带特性。为了避免复杂的边带分析，采用了幅度和频率解调分析方法。以封闭形式推导了幅度和频率解调谱方程，并揭示了它们的频率结构。针对基于上述理论推导的故障诊断，根据共振频率与运行工况的独立性，通过对变速过程中扭转振动的时频分析，提出了一种共振频率识别方法。通过数值模拟信号分析说明了理论推导和提出的方法，并通过动力学建模和实验室实验测试进一步验证。太阳、行星和齿圈的局部故障被成功诊断。
Planetary gearbox torsional vibration signals are free from the extra amplitude modulation effect due to time-varying transmission paths and have simpler frequency structure than translational ones. Gear faults result in modulation on the torsional resonance vibration and are manifested by the modulation feature. These merits are exploited for planetary gearbox fault diagnosis in this paper. Gear fault induced torsional vibrations in resonance region are modelled as amplitude modulation and frequency modulation (AM-FM) processes, the explicit equation of Fourier spectrum is derived, and the sideband characteristics are summarized. To avoid complex sideband analysis, amplitude and frequency demodulation analysis methods are exploited. The equations of amplitude and frequency demodulated spectra are derived in closed form, and their frequency structures are revealed. For fault diagnosis based on above theoretical derivations, a resonance frequency identification approach is proposed through time-frequency analysis of torsional vibrations during variable speed processes, according to the independence nature of resonance frequency on running conditions. The theoretical derivations and proposed approach are illustrated by numerical simulated signal analysis and are further validated through dynamics modelling and lab experimental tests. Localized faults on the sun, planet, and ring gears are successfully diagnosed.
