This article summarizes published journal articles on planetary and epicyclic gear dynamics
and vibration. Research in this field has increased dramatically over the past two decades …

Double planetary gear sets (DPGSs) are widely applied to high power and high torque
mechanical transmission systems due to the high loading capacity, steady transmission, and …

This article describes an interdisciplinary methodology to calculate the probability of failure
for bearing axial cracking, the dominant failure mode in the intermediate and high-speed …

This paper concentrates on the gear tooth crack detection by investigating the effects of tooth
crack on the vibration behaviors of a nonlinear spur gear system. Firstly, an analytical tooth …

This work developed a computational process to predict noise radiation from gearboxes. It
developed a system-level vibro-acoustic model of an actual gearbox, including gears …

Considering time-varying meshing stiffness, comprehensive gear error and piece-wise
backlash nonlinearities, a torsional nonlinear dynamic model of multistage gear of planetary …

A non-linear dynamic model of a fixed-axis spur planetary gear-rotor-bearing system for the
gearbox in Geared Turbofan (GTF) engine is established that considers the time-varying …

The operation environment of coal cutter gearboxes can be significantly harsher than that of
gear systems for general applications. The influence factors, including low speed, heavy …

This paper investigates the dynamics of wind turbine planetary gear sets under the effect of
gravity using a modified harmonic balance method that includes simultaneous excitations …

When the helical gear contains mixed modification, the backlash will vary along the tooth
width and tooth profile, which will lead to uneven contact of the meshing tooth pairs and …
