Study on Nonlinear Dynamic Characteristic of Gearbox Based on Explicit Dynamic

Abstract:

Considering the drawbacks of existing dynamics research of gearbox system, the dynamic analysis method based on perfectly elastic body is presented. A certain type of marine gearbox is taken as investigation object based on Abaqus/Explicit dynamic finite element program, the dynamic contact nonlinear model of gearbox system is established considering the coupling effect of each component, dynamic simulation of the gearbox system is carried out. The results show that, in the gearbox coupling model, the coupling effects among the bearing, the housing and the gears cause the dynamic characteristic of the gear transmission system more complex, which exacerbates shock effect of the gearbox, the model which considered coupling among the components is closer to the real working condition. The research has certain reference value for gearbox dynamic characteristic optimization.
