Anti-vibration structure of towering chimney
The invention relates to an anti-vibration structure for a towering chimney. The anti-vibration structure comprises a vibration reduction device and a vibration suppression device, the damping device is installed on the upper portion of the chimney and used for increasing damping and attenuating vibration. And the vibration suppression device is arranged on the vibration reduction device and is used for suppressing the generation of Karman vortex. On one hand, the vibration suppression structure is adopted to increase disturbance to resist wind load and form Karman vortexes on the surface of the chimney, resonance of the chimney is effectively avoided, and resonance is fundamentally reduced or avoided; on the other hand, the damping device is arranged, damping of the chimney is increased, force in the direction opposite to the vibration load is provided, the acceleration response of the chimney is reduced, the vibration amplitude is gradually attenuated, and therefore the damping effect is achieved. The device has the advantages of simple structure, easiness in installation, convenience in maintenance, economy and practicability.
本发明涉及一种高耸烟囱抗振结构，其包括：减振装置和抑振装置；所述减振装置安装在烟囱的上部，用于增大阻尼、衰减振动；且所述减振装置上设有所述抑振装置，所述抑振装置用于抑制卡门涡流的产生。本发明一方面采用抑振结构增加扰动抵抗风载荷在烟囱表面形成卡门涡旋，有效避免烟囱产生共振，从根本上减小或避免共振的发生；另一方面设置减振装置，增大烟囱的阻尼，提供与振动载荷相反方向的力，来降低烟囱的加速度响应，使振动幅度逐渐衰减，从而达到减振的效果。具有构造简单，易于安装，维护方便，经济实用的优点。
