摘要: 本文编制了可用于分析带有颤振主动抑制系统的机翼的根轨迹法程序。对自动判别颤振模态的方法进行了研究,提出了一种计算效率高、方法简单、编程容易的判别方法。通过算例表明,这种方法是可行的。

Abstract: A flutter analysis based on root locus method is programmed. It can be applied to a wing equipped with an active flutter suppression system. An automatic identification method of flutter modes is proposed which has the advantages of high efficiency in computation, brief algorithms and simplicity in programming. Numerical examples show that the method is feasible.
