Continuous Transient Impact Response Analysis of Drive Axle Housing

Abstract

Continuous transient impact response analysis of the drive axle housing was performed based on static analysis as the vehicle cross the obstacle. The whole process was divided into four stages. Both the static strength when the vehicle travels at constant speed and continuous transient impact response when the vehicle slowing down, climbing obstacle and falling back to the ground from the obstacle were calculated. The rigidity and strength of the drive axle housing in the whole process were analysed. The results indicate that the drive axle housing has excessive strength but insufficient rigidity. And the result also provides useful reference for optimization design and lightweight of drive axle housing.
