Rigidity and damping adjustable cylindrical high-rise structure wind vibration control tuned mass damper and design method and adjusting method thereof
The invention relates to a cylindrical high-rise structure wind vibration control tuned mass damper with adjustable rigidity and damping as well as a design method and an adjustment method of the cylindrical high-rise structure wind vibration control tuned mass damper. The annular moving mass unit is connected with the top of the chimney through the suspension unit, and the adjustable rigidity unit is arranged between the annular moving mass unit and the chimney structure and used for adjusting the overall rigidity and natural vibration frequency of the tuned mass damper. The adjustable damping unit is composed of a permanent magnet, a magnetic conductive iron plate and a conductive copper plate which are arranged on the lower surface of the annular motion mass unit and the annular fixed supporting platform, and the magnetic conductive iron plate on the annular fixed supporting platform is provided with a lifting nut. The distance between a conductive copper plate on the lower surface of the annular motion mass unit and a permanent magnet plate on the upper surface of the annular fixed supporting platform is adjusted, and then damping parameters of the tuned mass damper are adjusted. According to the tuned mass damper, the rigidity and damping parameters of the tuned mass damper can be adjusted on site, and therefore the wind vibration control efficiency of the tuned mass damper is improved.
本发明涉及一种刚度和阻尼可调的圆柱形高耸结构风振控制调谐质量阻尼器及其设计方法、调节方法。环形运动质量单元通过悬挂单元与烟囱顶部相连，环形移动质量单元与烟囱结构之间设置可调刚度单元，用于调整调谐质量阻尼器整体刚度和自振频率。可调阻尼单元由环形运动质量单元下表面和环形固定支撑平台上设置的永磁铁、导磁铁板和导电铜板组成，环形固定支撑平台上的导磁铁板设有升降螺母，用于调节环形运动质量单元下表面导电铜板和环形固定支撑平台上表面永磁体板之间的距离，进而实现调谐质量阻尼器阻尼参数的调节。本发明涉及的调谐质量阻尼器可在现场对其刚度和阻尼参数进行调整，从而提升调谐质量阻尼器风振控制效率。
