将可靠性优化设计理论、可靠性灵敏度技术与稳健设计方法相结合,讨论了具有非正态分布参数的车辆零件的可靠性稳健设计问题,提出了可靠性稳健设计的计算方法。把可靠性灵敏度溶入可靠性优化设计模型之中,将可靠性稳健设计归结为满足可靠性要求的多目标优化问题。在基本随机参数的前四阶矩已知的情况下,通过计算机程序可以实现具有非正态分布参数的车辆零件的可靠性稳健设计,迅速准确地得到具有非正态分布参数的车辆零件的可靠性稳健设计信息。数值算例表明所提出的方法是一种非常方便和实用的可靠性稳健设计方法。

The reliability-based optimization, the reliability sensitivity technique, and therobust design are employed to present a practical and effective approach of robust reliabilitydesign for mechanical components on the condition of known probabilistic characteristics oforiginal random variables. The theoretical formula of robust reliability design for mechanicalcomponents is obtained. The respective program can be used to obtain the robust reliabilitydesign parameters accurately and quickly. According to the numerical results, the methodproposed is a convenient and practical robust reliability design method.

较好地解决了具有独立失效模式的多自由度非线性随机参数振动系统的可靠性灵敏度分析问题.应用四阶矩技术和Edgeworth级数把未知的响应和状态函数的概率分布展开成标准的正态分布的表达式,从而确定了系统的可靠度和可靠性灵敏度,并放松了随机参数的分布概型和激励类型.

【期刊论文】Reliability-based design of automobile components
张义民, Y Zhang*, and Q Liu
Proc Instn Mech Engrs Vol 216 Part D: J Automobile Engineering,-0001,():
-1年11月30日
Techniques from the perturbation method, the second moment and reliability-based design theory are employed to present a practical and effective method for the reliability-based design of automobile components. The theoretical formulae of reliability-based design of automobile compo-nents are obtained. The reliability-based design methods are employed to develop the reliability design of atttomobile axles and springs. The corresponding program can be used to obtain the reliabilit\-based desien parameters of automobile components accurately and quickly,
