Transient dynamic analysis of high power density gear transmission

Abstract

In this paper, the dynamic problem of high power density gear transmission in transient state is studied based on flexible multi-body model. First, the flexible gear transmission multi-body model is built with the detailed formula of contact force and component modes synthesis method. Second, the transient time as dynamic external excitation is undertaken for high power density gear transmission, which has larger flexibility than others. Numerical and theoretical results confirm a significant influence of transient state on the dynamic force and deformation. Furthermore, the reasonable time of gear transmission transient state can be avoided the great impact force, reduce vibration and noise in gear system. Consequently, the transient time of gear transmission is an innegligible excitation factor for gear transmission.
