Vertical tuned mass magnetic lead screw type inerter eddy current damper
The invention relates to a vertical tuned mass magnetic lead screw type inerter eddy current damper. The vertical tuned mass magnetic lead screw type inerter eddy current damper comprises a spring mass system, an inertia mass system, an eddy current damping system and a supporting system; the spring mass system comprises a spring and a clump weight; the inertia mass system comprises a flywheel, amagnetic lead screw nut pair and a magnetic suspension thrust bearing; the eddy current damping system comprises a straight-strip-shaped permanent magnet, a conductor plate and back iron; and the supporting system comprises guide rods, a supporting bracket and an outer frame. According to the damper, the inerter principle is introduced, physical balance weight is reduced, the net elongation of thespring of a low-frequency structure controlled by the device is reduced while the mass ratio of the device is increased; by adopting the magnetic lead screw nut pair, the friction between a lead screw and a nut is eliminated, and the working efficiency is improved; meanwhile, the magnetic suspension thrust bearing is used cooperatively to ensure that the flywheel is suspended in a flywheel chamber to work normally; and the overall friction of the damper is greatly reduced, and the service life is prolonged.
本发明涉及一种竖向调谐质量磁力丝杠式惯容电涡流阻尼器，包括弹簧质量系统、惯性质量系统、电涡流阻尼系统和支承系统。其中所述弹簧质量系统包括弹簧和配重块，惯性质量系统包括飞轮、磁力丝杠螺母副以及磁悬浮推力轴承，所述电涡流阻尼系统包括直条永磁铁、导体板和背铁，所述支承系统包括导杆、支撑托架和外框架。本发明阻尼器引入了惯容原理，减轻了物理配重，实现提升装置质量比的同时降低装置控制低频结构的弹簧净伸长量。本发明采用磁力丝杠螺母副，消除了丝杠与螺母之间的摩擦，提高了工作效率。同时配合使用磁悬浮推力轴承，保证飞轮悬浮在飞轮室中正常工作。所述阻尼器整体摩擦大大减小，延长了使用寿命。
