工程结构粘滞流体阻尼器的减振机制与控振分析

Analysis of Controlling Vibration Responses of Viscous Fluid Damper for Engineering Structures

在对粘滞流体阻尼器的构造及阻尼孔的阻尼特性进行分析的基础上 ,建立了粘滞流体阻尼器的阻尼力与速度的关系式 ,并对某一设置粘滞流体阻尼器的 5层框架进行了控振分析 。

Based on the analysis of the construction of viscous fluid damper and its damping characteristics, a formula of the relation between the damping force and the speed of damper is proposed,and the dynamic responses of a five storey frame equipped with a viscous fluid damper are calculated. The result confirms that viscous fluid damper operates well in controlling and lessening vibration of engineering construction.
