引言有一句格言说,“对于气动弹性与控制的耦合而言,事实多于予言。”在过去的十年中间,常常有这样的事,即工程师们必须不断地,经常是痛苦地想起:刚性结构与其说是一种通常的情况,倒不如说是一种例外。但这并不是说,在这之前,仅仅存在着刚性结构。然而,随着高性能飞机及其衍生物——导弹和航天器的出现,对于重量轻的非刚性结构的要求增加了。现在的机身结构要碰到多种类型的动力学现象,其中有一些是人们所不希望的。为了邦助或代替人来控制刚体

There is a saying in the introduction that there is “more truth to the coupling between aeroelasticity and control.” In the past decade or so there has always been something that engineers must constantly and often painfully recall: rigidity Structure is not so much a normal case as it is an exception. This does not mean, however, that before that there was only a rigid structure. However, with the advent of high-performance aircraft and its derivatives, missiles and spacecraft, the need for lightweight, non-rigid structures increases. The current structure of the fuselage to encounter many types of kinetic phenomena, some of which are people do not want. To control or replace human body to rigid body
