摘　　要：在可靠性优化设计理论与可靠性灵敏度分析方法的基础上,讨论了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数值计算方法.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.In the paper, based on the reliability-based design optimization theory and the reliability sensitivity analysis method, the reliability-based robust design for coil tube-spring 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.
