摘要
本文从理论上分析了拦污栅结构的流固耦合振动，提出了考虑流固耦合振动设计的栅振频率与过栅流速之间的简单关系，并通过实例对流固耦合和不考虑流固耦合的计算方法的差异进行了比较，结果说明在一定范围内。
The trashrack attached to a high dam is subjected to earthquake and hydrodynamic exciting. The vibration induced by fluid-structure interaction affects trashrack life frequently due to amplification of vibration, resonance, flutter fatigue, and so on. In this paper the vibration response induced by the fluid-structure interaction of trashrack is studied and the relationship between the frequency of trashrack and the flow velocity is established. The efficiency of this method is shown by one working example .
