Abstract

The major goal in this work is to improve the planetary gear dynamic model presented in the diseration by Jian Lin presented in the Ohio State University in 2000 . A lumped-parameter model is built for the dynamic analysis of general planetary gears.
In this paper, the meshing stiffness and damping are modelled as time varying parameters. Mathematical model that consideres time-varying stiffness and viscous damping of the meshing tooth pair is proposed. Gear errors are also included in the theory and in numerical applications. A computer software in Visual Delphi was designed as well. It enable for the mathematical model on the planetary gear system to be solved.
