摘　　要：将可靠性优化设计理论、可靠性灵敏度分析技术与鲁棒设计方法相结合,讨论了具有不完全概率信息的螺旋管簧的可靠性鲁棒设计问题,提出了可靠性鲁棒设计的计算方法。把可靠性灵敏度溶入可靠性优化设计模型之中,将可靠性鲁棒设计归结为满足可靠性要求的多目标优化问题。Based on the reliability-based optimization design theory, the reliability sensitivity technique and the robust design method, the reliability-based robust design of coil tube-spring under incomplete probability information is extensively discussed and a numerical method for reliability-based robust design is proposed. The reliability sensitivity is added to the reliability-based optimization design model and the reliability-based robust design is described as a multi-objection optimization.
