It adopts the multi-tooth vibration separation method to provide methodological support for fault diagnosis of planetary gear transmission systems. Based on the meshing impact mechanism, the meshing impact dynamics is calculated, and the effects of different factors on the meshing impact force are analyzed. An analytical signal model is constructed based on the sideband modulation mechanism, and signal analysis of the gearbox is conducted using friction dynamics, with the influence of gear root cracks under friction on TVMS considered, namely the simulation results of the effect of rotation angle on meshing stiffness. Furthermore, the variation of TVMS under different rotation angles is analyzed, and the time-domain waveforms and Fourier spectrum diagrams of the synthesized signal are obtained through simulation. Signal collection experiments are performed to obtain time-domain waveforms and Fourier spectrum diagrams under different lubrication conditions. The feasibility of the method is verified by comparing the simulation data results with the experimental data results.
