应用汽车零部件可靠性稳健优化设计的理论方法，对汽车典型轴系零部件，如半轴、前轴和后桥进行了可靠性稳健优化设计，给出了计算仿真分析结果，为工程实际的汽车零部件的可靠性稳健优化设计提供了理论依据。

Using the theoretical method of reliability-based robust optimization design (in Part 1), several axles in automobiles, such as half-axle, front-axle and back-axle housing are computed and the emulation results are analyzed. According to the method presented in this paper, the reliability-based robust optimization designs for automobile components in practical engineering are obtained.
