摘要
为了反映同一型号的一批飞机颤振临界速度本身固有的随机性质，本文提出了一种与序列响应面算法相结合的颤振速度可靠性分析方法。并以此为基础，发展了一个可用于机翼颤振临界速度可靠性分析的计算机程序RFL。文中给出了包括K8、Q5机翼在内的若干算例，证实了所述方法与程序的实用性。
To show the random nature of flutter critical speed of same type and aircraft in one batch, the anthor of this paper advances a method for reliability analysis of flutter speed combined with sequence response surface algorithm, based on which, computer program RFL is developed for reliability analysis of wing flutter critical speed. The practicality of the method and procedure are proved by severel algoristic examples including those for wing of K-8 and A 5 aircreft.
