Tuned mass damper vibration reduction control device suitable for vibration reduction track
The invention discloses a tuned mass damper vibration reduction control device suitable for a vibration reduction track, which comprises a vibration reduction track clamping groove (3), a steel plate (4), a damping unit and four springs (13), and is characterized in that the vibration reduction track clamping groove (3) comprises a fixing screw rod (31) used for fixing the vibration reduction track clamping groove (3) on a vibration reduction track cross beam (2); the damping unit comprises an upper damping cylinder (16), a lower damping cylinder (15) and a liquid damper (18) stored in the lower damping cylinder, and the upper end of the upper damping cylinder is fixed to the lower surface of the vibration reduction rail clamping groove. The lower part of the upper damping cylinder is inserted into the lower damping cylinder; the lower damping cylinder comprises a lower end plate (151); the upper ends of four springs (13) are respectively fixed on the lower surface of the damping track clamping groove so as to surround the periphery of the upper end of the upper damping cylinder; the lower ends of the four springs are respectively fixed on the corresponding upper surfaces of the end plates; and the steel plate is fixed on the lower surface of the lower end plate, so that a mass-spring-damping vibration attenuation system is formed.
本发明公开了一种适用于减振轨道的调谐质量阻尼器减振控制装置，包括减振轨道卡槽(3)、钢板(4)、阻尼单元以及四个弹簧(13)，减振轨道卡槽(3)包括固定螺杆(31)，用于将减振轨道卡槽(3)固定在减振轨道横梁(2)上；阻尼单元包括上阻尼筒(16)、下阻尼筒(15)及存储在下阻尼筒中的液体阻尼(18)，上阻尼筒的上端固定在减振轨道卡槽的下表面上；上阻尼筒的下部插入到下阻尼筒之中；下阻尼筒包括下端板(151)；四个弹簧(13)的上端分别固定在减振轨道卡槽的下表面上，以围绕在上阻尼筒的上端周围；四个弹簧的下端分别固定在端板的相应上表面上；钢板固定在下端板下表面上，由此构成质量‑弹簧‑阻尼减振系统。
