Lever type tuned mass damper
The invention discloses a lever type tuned mass damper which comprises a bottom plate, a pivot base, a lever, a damper, a spring and a mass block. The lever is rotatably connected to the pivot seat, so that the lever can rotate relative to the pivot seat, the mass block is fixedly connected to the lever, the damper is located between the lever and the bottom plate, two ends of the damper are slidably connected to the bottom plate and the lever separately, so that the position of the damper can be adjusted to adjust the position, relative to the bottom plate, of the damper so as to change an arm of force of the damper on the lever, thereby adjusting the frequency of a whole TMD system. The lever type tuned mass damper is large in frequency adjusting range and solves the problem that the tuned mass damper is relatively small in frequency adjusting range.
本发明公开了一种杠杆式调频质量阻尼器，包括底板、支点座、杠杆、阻尼器、弹簧和质量块，通过所述杠杆与所述支点座转动连接，使得所述杠杆能够相对于所述支点座进行转动，所述质量块与所述杠杆固定连接，所述阻尼器位于所述杠杆和所述底板之间，且所述阻尼器的两端分别与所述底板和所述杠杆滑动连接，使得所述阻尼器的位置可以调节，调节所述阻尼器相对于所述底板的位置，从而改变所述阻尼器在所述杠杆上的力臂，以对整个TMD系统的频率进行调整，且能频率调节范围大，解决了调频质量阻尼器频率调节范围较小的问题。
