摘要： 驱动桥壳轻量化设计对于提高承载能力、降低生产成本具有重要的意义.本文在驱动桥壳有限元分析和疲劳分析计算的基础上建立驱动桥壳多目标优化模型，对重型卡车驱动桥壳进行参数化设计，建立正交试验表，利用田口方法和综合评价方法对驱动桥壳的疲劳性能稳健性和质量进行优化设计.优化结果表明，此方法可以应用于驱动桥壳的多目标优化，优化后驱动桥壳的疲劳稳健性能得到提高，减轻了质量，因此节约了桥壳材料，降低了生产和运营成本，提高了设计水平.

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
