Abstract EN
The gear damage will induce modulation effects in vibration signals.
A thorough analysis of modulation sidebands spectral structure is necessary for fault diagnosis of planetary gear set.
However, the spectral characteristics are complicated in practice, especially for a multistage planetary gear set which contains close frequency components.
In this study, a coupled lateral and torsional dynamic model is established to predict the modulation sidebands of a two-stage compound planetary gear set.
An improved potential energy method is used to calculate the time-varying mesh stiffness of each gear pair, and the influence of crack propagation on the mesh stiffness is analyzed.
The simulated signals of the gear set are obtained by using Runge-Kutta numerical analysis method.
Meanwhile, the sidebands characteristics are summarized to exhibit the modulation effects caused by sun gear damage.
At the end, the experimental signals collected from an industrial SD16 planetary gearbox are analyzed to verify the theoretical derivations.
The results of experiment agree well with the simulated analysis.
