Tuned mass damper with continuously adjustable rigidity
The invention discloses a tuned mass damper with continuously adjustable rigidity. The tuned mass damper comprises a mass block, a long guide rod, a short guide rod, a linear bearing, a connecting plate, a supporting plate, an L-shaped limiting steel plate and a spiral steel spring, wherein the long guide rod penetrates through the four corners of the mass block, the top end of the long guide rod is connected with an upper top plate, and the lower end of the long guide rod is connected with a lower bottom plate; the long guide rod is sleeved with the linear bearing, and the upper end of the linear bearing is connected with the mass block; the short guide rod is sleeved with the spiral steel spring, the upper end of the spiral steel spring is connected with a top block, and the lower end of the spiral steel spring is connected with the linear bearing; the left end and the right end of the connecting plate are connected with the linear bearing; the upper end of the supporting plate is connected with the connecting plate, and the lower end of the supporting plate is connected with the L-shaped limiting steel plate; and the L-shaped limiting steel plate is arranged on the bottom plate. According to the tuned mass damper, the rigidity and frequency of the damper can be continuously adjusted by moving the supporting plate, the standard unification of the spring specification can be achieved due to the fact that the rigidity is continuously adjustable, the machining period of the tuned mass damper in practical engineering use is greatly shortened, and the manufacturing cost is reduced.
本发明公布了刚度连续可调的调谐质量阻尼器，包括质量块、长导杆、短导杆、直线轴承、连接板、支板、L型限位钢板和螺旋钢弹簧；所述长导杆穿过质量块的四个角部，顶端和上顶板连接，低端和下底板连接，所述直线轴承套在长导杆上，其上端和质量块连接，所述螺旋钢弹簧套在短导杆上，其上端和顶块连接，下端和直线轴承连接，所述连接板左右两端和直线轴承连接，所述支板上端与连接板连接，下端与L型限位钢板连接，L型限位钢板置于底板上。本发明可以通过移动支板的位置实现阻尼器刚度和频率的连续调节，并由于刚度连续可调，可以实现弹簧规格的标准统一化，大大缩短了调谐质量阻尼器在实际工程使用中加工的周期，并降低制造的成本。
