本文研究了弹性飞机的颤振主动抑制就颤振发生的实质的讨论,提出一种研究颤振问题的探索性想法,即把对全系统颤振问题的研究归结到对其中少数有关的运动模态特性的研究。此一想法在颤振特性分析及颤振主动抑制方面得到具体的发挥,相应地产生了一种综合作图法和解析法特点的近似分析颤振特性的途径和一个具有明确物理意义的优化目标函数。后者一定程度上克服了常用的二次型优化方法所固有的某些弊病。算例结果表明本文提出的建议和方法具有一定的使用价值。 In this paper, we study the essence of flutter suppression in flexible aircraft and put forward an exploratory idea to study the flutter problem. At the same time, we study the whole system flutter problem attributed to a few related motion modules Study of state characteristics. This idea has been specifically demonstrated in terms of chatter characteristics and active suppression of chatter, resulting in a way of approximating the flutter charac- teristics that combines the features of the mapping and parsing methods and a well-defined objective of optimization function. The latter overcame some of the drawbacks inherent in commonly used quadratic optimization methods. The result of the example shows that the suggestions and methods proposed in this paper have certain value in use.
