| 摘 要： | 并列圆柱体在均匀流场中的涡激振动十分复杂，但又广泛存在于实际工程之中。当两柱在流体激励作用下产生振动时，由于同时存在着流固耦合作用和柱间干扰作用，而使周围流场变得更加复杂。本文对并列刚性和弹性圆柱的流场分类，Ｓｔｒｏｕｈａｌ数及流体载荷等问题进行了综述，在此基础上提出了进一步研究的建议。

| Abstract: | The Vortex in duced vibration for two circular cylinders in side by side arrangement is very complex, but exists extensively in practical engineering. When two Cylinders are elastic and vibrate in flow. the flow flied arround two circular aylinders will become significiantly more complicated because of both the interaction of the flow field and the cyhinder motion and the interference between two cylinders. This paper presents an overview of the problems including different flow regimes. Strouhal numbers. flwid force and dynamic responses for two cylinders in side by side arrangement. In addition,futrure research needs are disscussed in this paper. |
