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。
In order to reflect the random nature inherent in the flutter critical speed of a batch of aircraft of the same model, a method of flutter velocity reliability analysis combined with the sequence response surface algorithm is proposed in this paper. Based on this, a computer program RFL that can be applied to the reliability analysis of wing flutter critical speed is developed. A few examples including the wings of K8 and Q5 are given in this paper, which prove the practicability of the method and program.
