Abstract

This paper brought out a new dynamic modeling and analysis method on rigid-flexible coupling of gear meshing. Based on Multi-body Dynamics Theory and Compliant Contact Dynamics, we proposed three dimensional contact dynamic model of gear meshing with factors such as flexible deformation between teeth and gear body, discrete contact surface with discrete involute profile and geometrical parameters. Apply numerical simulation and vibration analysis to research on contact vibration of gear meshing with the effect of single surface contact, double surface contact of meshing teeth and characteristics of rigid and flexible coupling. We got contact force and moment in full surface of meshing teeth and speed of driven gear and so on. The results revealed that the new method and dynamic model brought out in this paper could effectively deal with vibration response analysis of gear meshing with the effect of flexible and three dimensional contact of gear meshing. The method and simulation results provide basic data and valuable theoretical basis for further research on dynamics characteristics of gear transmission systems.
