摘　　要：工程结构中的复合材料层合板的几何参数往往具有随机性质.如何研究随机参数层合板的灵敏度,并对参数进行优化分析,这对正确估计结构设计的可靠性有着非常重要的意义.用随机摄动法,导出了求反对称层合板响应灵敏度的计算公式,研究了随机参数反对称层合板响应的灵敏度和优化设计,并用网络法计算出最佳铺层角.The geometric parameters of composite material laminated plates are usually random due to the effect of various undeterministie factors in engineering structure. The study of the sensitivity of random parameter laminated plates and the analysis of its optimum design. Of parameter play an important role in the right estimation of the reliability of construction design. This article leads to the calculation formula of responding sensitivity of antisymmetrically laminated plates and studies the responding sensitivity and optimum design of random paramter of antisymmetrically laminated plates, by using random perturbation law. It uses the mesk law to calculate the best angle of araning lamination.
