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.
The chimneys of thermal boilers belong to towering structures and are located in such chimneys with large wind loads, so there is a greater possibility of deformation and destruction due to wind-induced vibration. As an effective vibration control device, the suspended frequency-modulated mass damper adopts a reasonable Structure and layout position, applied to the high-pressure area of the thermal boiler chimney, which can effectively reduce the wind vibration caused by the dynamic response to ensure the safety of the entire thermal boiler. Combined with a specific project before and after the installation of FM-quality damper Wind vibration analysis and design applications, for similar projects provide a reference for the experience.
