Dynamic Analysis of Gear Systems with Dynamic Mesh Stiffness and Time- Varying Bearing Stiffness
Nonlinear DynamicsAbstract In this study, a novel analytical model for dynamic mesh stiffness of spur gears is developed using variable cross-section beam theory, explicitly accounting for driving speed effects. The dynamic mesh stiffness is determined by applying the modal superposition method to analytical model equations, and subsequently validated using both

A Model for Analysis of Time-Varying Mesh Stiffness of Helical Gears with Misalignment Errors
Transactions of FAMENA, 2021 A mathematical model is proposed to calculate the time-varying mesh stiffness (TVMS) of helical gears under the condition of gear misalignment by combining the slice method. The proposed method aims to reveal the influences of different misalignment errors (centre distance error, action plane error and off action plane error) on the TVMS of helical ...
