Analysis on Dynamic Contact Force in High Power Density Gear Transmission Based on Flexible Model

Abstract:

Recently, most of researchers pay more attention to the flexible model for solving dynamic contact force in high power density gear transmission. But, the detailed formula of the contact force parameters is not given. Therefore, in this paper the detailed calculation of coefficient of restitution (COR) is proposed, which can solve the elastoplastic contact deformation problems compared with other method. To improve the simulation efficiency, a flexible model based on ADAMS and Hertzian theory is presented. According to the simulation results, the normal contact force of the flexible model is much higher than that of the rigid model in plastic contact deformation. Meanwhile, the normal contact force delay exists in flexible model compared with rigid model. At last, the flexible model simulation results are close to the theoretical result in steady state. Consequently, the flexible model can be applied to analyze dynamic characteristic in reasonable time and many revolutions of the high power density gear transmission.
