Low-frequency lever type tuned mass damper
The invention discloses a low-frequency lever type tuned mass damper. The damper comprises a lever frame (1) which comprises a lever support (11) and a lever suspension arm (12), a fixing mechanism (6) vertically connected with the lever frame (1) and internally provided a spring assembly (2) and a damper body (5); and a mass unit (3) arranged at the end, far away from the fixing mechanism (6), ofthe lever cantilever (12). The mass unit (3) is movably connected with the lever cantilever (12) through a bearing (4), the mass unit (3) and the lever cantilever (12) form a tuned mass damper powerand power arm, and the spring assembly (2), the damper body (5) and the part between the lever cantilever (12) and the lever support (11) form a resistance and resistance arm. The mass unit (3) comprises a mass block (31). According to the tuned mass damper, the main structure can be effectively prevented from being damaged due to large-amplitude vibration, and then the main structure is protectedagainst damage.
本发明公开了一种低频杠杆式调谐质量阻尼器，包括杠杆框架(1)，其包括杠杆支架(11)及杠杆悬臂(12)；与杠杆框架(1)垂直连接的固定机构(6)，固定机构(6)内设有弹簧组件(2)及阻尼器(5)，杠杆悬臂(12)远离所述固定机构(6)的一端设有质量单元(3)，该质量单元(3)通过轴承(4)与所述杠杆悬臂(12)活动连接，质量单元(3)及杠杆悬臂(12)构成调谐质量阻尼器动力及动力臂，弹簧组件(2)、阻尼器(5)及杠杆悬臂(12)至所述杠杆支架(11)之间部分构成阻力及阻力臂；且所述质量单元(3)包括质量块(31)。本发明的调谐质量阻尼器，可有效避免主结构因大幅度振动而发生破坏，进而保护主结构不受损坏。
