【摘要】 讨论了随机参数服从任意分布时拉杆的可靠性优化设计问题。在基本随机参数的前四阶矩已知的情况下,应用随机摄动法和Edgeworth级数方法对拉杆进行可靠性优化设计,通过计算机程序可以实现随机参数服从非正态分布的拉杆可靠性优化设计,迅速准确地得到了拉杆的可靠性优化设计信息。更多还原

【Abstract】 Optimization design of drag rod reliability with random distributed parameters is discussed.With the first four orders of basic random parameters known,optimization design of drag rod reliability are done with the random perturbation method and the Edgeworth series method.By use of computer programs,optimization design of drag rod reliability when random parameters comply with abnormal distribution can be done and accurate reliability optimization information is immediately obtained.更多还原
