| 摘 要： | 考虑曳引机主传动机构——蜗杆副中的各种不确定因素,根据其失效形式建立了可靠性分析模型;对蜗杆副进行了可靠性分析及可靠性灵敏度分析,确定了随机变量对可靠度的影响程度.针对获得的可靠性结果,对蜗杆副实施优化设计,使机构得到了改善,并获得了合适的可靠性指标;将可靠性灵敏度引入优化模型,使得可靠性稳健设计归结为满足可靠度要求的多目标优化问题.通过实际算例验证了该方法的实用性与有效性.

| Abstract: | Considering the uncertain influencing factors on the worm-gear pair as the main transmission mechanism of traction machines,the reliability modes were developed on the basis of its failure modes.The reliability and its sensitivity of the worm-gear pair were analyzed to determine the impacts of mutative random variables on the reliability.Then,the design of the pair was optimized to improve the main transmission mechanism with an appropriate reliability index.Introducing the reliability sensitivity into the ... |
