Dynamic Simulation of Gear Transmission

Han Zhennan

Abstract

This paper studies the backlash nonlinear vibration problem for a gear pair,by analyzing comprehensively the influence of meshing impact excitation,time-varying meshing stiffness and error loading on gear transmission system.Based on the definition of torsional mesh stiffness,the 3D contact models for defect-free and defective gear transmission were set up respectively.The torsional mesh stiffness values in different contact position under the two kinds of running conditions were calculated.The paper establishes the nonlinear dynamic model of the gear-pair and solves the dynamic equations by the Runge-Kutta.
