Tuned mass damper for tower
The invention discloses a tuned mass damper for a tower. The tuned mass damper comprises a mass ball suspended in a tuned mass damper body, a hemispherical plate arranged in the tuned mass damper body and positioned below the mass ball, and a plurality of elastic mechanisms used for connecting the mass ball with the side wall of the tuned mass damper body and uniformly distributed in the circumferential direction; each elastic mechanism is composed of a damper and a spring arranged outside the damper in a sleeving mode, and universal joints are arranged at the two ends of each elastic mechanism; and the tuned mass damper body is composed of a top cover plate, a bottom fixing ring and a plurality of vertical supporting rods which are used for connecting the top cover plate and the bottom fixing ring and are evenly distributed in the circumferential direction. According to the tuned mass damper, omnidirectional tuning can be realized, the structure is simple, the construction is convenient, dynamic response control can be effectively carried out on the wind load vortex-induced vibration of a flexible tall tower, and the safety and reliability of the flexible tall tower are ensured.
本发明公开了一种用于塔器的调谐质量阻尼器，包括：悬吊在调谐质量阻尼器本体中的质量球；设置在调谐质量阻尼器本体内且位于质量球下方的半球形板；将质量球与调谐质量阻尼器本体的侧壁相连接的若干个沿周向均匀分布的弹性机构；弹性机构由阻尼器和套设在阻尼器外部的弹簧构成，且弹性机构的两端均设有万向节；调谐质量阻尼器本体由顶部盖板、底部固定环以及用于连接顶部盖板和底部固定环的若干根沿周向均匀分布的竖直支撑杆构成。本发明可实现全向调谐，结构简单，施工方便，可有效对柔性高耸塔器的风载涡激振动进行动态响应控制，保证柔性高耸塔器的安全可靠性。
