摘要
热力锅炉烟囱属于高耸结构,处于风力荷载较大区域的此类烟囱,存在着因风振引起的变形和破坏的较大可能.悬挂式调频质量阻尼器作为一种有效的振动控制装置,采用合理的构造方式与布置位置,应用在高风压区的热力锅炉烟囱上,可有效降低其风振引起的动力反应,保证整个热力锅炉的安全.结合一个具体工程项目加装调频质量阻尼器前后的风振分析与设计应用,为同类项目提供了可供参考的经验.
Heating power boiler is a kind of towering structure. There are more possibilities of deformation and damage for this kind of boiler under high wind power. Suspended tuned mass damper can be used for the heating power boiler in high wind pressure zone to control the dynamic reaction. It acts as an effective vibration control device, as well as a safeguard for the heat boiler, if it has a reasonable structure and layout position. The effect was proved by a specific engineering analysis and application when the TMD is fixed up correctly and reasonably, which can provide a useful reference for the similar projects.
