将可靠性优化设计理论与可靠性灵敏度分析方法相结合，讨论了汽车零部件的可靠性稳健优化设计问题，提出了可靠性稳健优化设计的计算方法。把可靠性灵敏度融入可靠性优化设计模型之中，将可靠性稳健优化设计归结为满足可靠性要求的多目标优化问题。

In the paper, based on the reliability-based design theory and the reliability sensitivity analysis method, the reliability-based robust optimization design for automobile components is extensively discussed and a numerical method for reliability-based robust optimization design is presented. The reliability sensitivity is added to the reliability-based optimization design model and the reliability-based robust optimization design is described as a multi-objective optimization.
