Dynamic Simulation of Gear Meshing Force Based on ADAMS

Abstract

It proposes a method for dynamic simulation of gear meshing force on the basis of dynamics analysis software ADAMS in the paper. Three dimensional solid model of parametric helical gear is built by using PRO/E. The data conversion between PRO/E and ADAMS has been realized. The parameters in contact force are confirmed based on the Hertz elastic impact theory. The gear meshing process has been simulated and analyzed by using mechanical system dynamic simulation software ADAMS. The change regulation of meshing force in the time-domain and frequency-domain has been researched under different speed conditions. It is proved that the meshing force of gears can be accurately simulated by using ADAMS. The simulation results of meshing force can provide basic data for the next gear strength analysis. It also can provide the reference for the analysis of gear dynamic optimization, fatigue and stiffness.
