摘要:
介绍了结构控制和消能减振技术的减振机理和减振设计方法,对不同结构构造的粘滞流体阻尼器的耗能原理进行了研究,研制出了一种性能稳定的双出杆型工程结构减振粘滞流体阻尼器.研究表明,研制的粘滞流体阻尼器是一种无刚度的速度相关型阻尼器,阻尼器的阻尼力与活塞的运动速度近似呈线性关系.对一栋顶部设置有钢塔的高层建筑实施了减振控制,计算结果表明,流体阻尼器可有效地降低结构在强震和大风下的振动反应,是一种性能良好的消能减振装置.
Abstract:
The principle and design method of vibration energy dissipation and structural control are introduced. The conformation and energy dissipation principles of various fluid viscous dampers were studied and a kind of high-performance damper, i.e. fluid viscous damper with double guide bars, was developed and manufactured. Based on the study and experiment, it is concluded that this fluid viscous damper for vibration energy dissipation is a kind of velocity related damper without rigidity. The relationship between the damping force and the velocity is approximately linear. With fluid viscous damper, the structural vibration energy dissipation control of a high-rise building with a steel tower on its roof was carried out. The computing results prove that the fluid viscous damper can effectively reduce the structure vibration response induced by earthquake and wind. It is a high-performance structural vibration energy dissipation device.
