Abstract: Lightweight of driving axle housing is of great importance to enhance load capacity and reduce production cost. In this paper, multi-objective optimal model was built on the basis of finite element and fatigue analysis of driving axle housing. The orthogonal test table was established as parametric design of driving axle housing. The fatigue robustness and lightweight of the driving axle housing were optimized by Taguchi method and comprehensive evaluation method. The optimization result shows that this method can be applied to the multi-objective optimization of driving axle housing. The optimized driving axle housing has a better performance in fatigue robustness with light weight. The material of driving axle housing is saved, the production and operating cost is reduced, and the design level is thus improved.

Key words: multi-objective optimization, Taguchi method, comprehensive evaluation method, fatigue robustness optimization, lightweight design
