摘　　要：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级数方法对钢板弹簧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钢板弹簧可靠性优化设计,迅速准确地得到了钢板弹簧的可靠性优化设计信息。Under the condition of knowing the first four ordered matrixes of basic random parameters, to carry out relia bility optimization design on steel plate spring by adopting random perturbation method and Edgeworth progression method. By means of computer program the reliability optimization de sign of steel plate spring can be realized with its random pararneters obey the non orthostate distribution, thus the information of reliability optimization design of steel plate spring was rapid-ly and accurately obtained.

关 键 词：钢板弹簧 可靠性优化设计 摄动法 任意分布参数
