Triangular prism type tuned mass damper suitable for large-span cantilever structure
The invention relates to a triangular prism type tuned mass damper suitable for a large-span cantilever structure, which comprises a triangular prism box body (1), a particle damping unit (4) and a steel mass block (3), wherein the particle damping unit (4) and the steel mass block (3) are arranged in the triangular prism box body (1), and a high-damping spring (2) is arranged below the triangular prism box body (1). The particle damping unit (4) comprises a particle damping cavity (5), three kinds of particle balls with different sizes and a foaming rubber pad (9). When the vibration amplitude of the structure is small, the particle balls extrude the foaming rubber pad and roll to consume energy; when the vibration amplitude of the structure is large, the particle balls extrude the foamed rubber through collision to dissipate energy. Compared with the prior art, while a staged energy consumption mechanism is achieved, the problems that a traditional tuned mass damper is narrow in vibration reduction frequency band and large in movement stroke, and noise is generated due to particle collision are solved.
本发明涉及一种适用于大跨悬挑结构的三棱柱型调谐质量阻尼器，包括三棱柱箱体(1)、设于三棱柱箱体(1)内的颗粒阻尼单元(4)和钢质量块(3)，三棱柱箱体(1)的下方是高阻尼弹簧(2)。所述颗粒阻尼单元(4)包括颗粒阻尼腔室(5)，三种不同大小颗粒球以及发泡橡胶垫(9)。当结构振动幅度较小时，颗粒球通过挤压发泡橡胶垫和滚动耗能；当结构振动幅度较大时，颗粒球通过碰撞挤压发泡橡胶耗能。与现有技术相比，本发明在实现分阶段耗能机制的同时，解决了传统质量调谐阻尼器减振频带窄，运动行程大，以及颗粒碰撞产生噪音的问题。
