Pinion and rack type self-resetting eddy current damper
The invention belongs to the technical field of civil engineering structure damping, and relates to a gear and rack type self-resetting eddy current damper which comprises a protection cover, at least one set of permanent magnets, a piston rod, a gear, a conductor rotating disc and a pressed spring. The piston rod is inserted into the protective cover and meshed with a gear rotationally installed in the protective cover, the piston rod is movably connected with the protective cover so that the piston rod can move in the axial direction of the piston rod, and a piston rod connecting piece used for being connected with an external controlled structure is arranged at the end, away from the protective cover, of the piston rod. The conductor turntable is fixedly connected to the gear to rotate along with the gear and cut magnetic induction lines to form an eddy current damping effect, and the size of the conductor turntable is at least 10 times that of the gear; the two compressed springs are installed between the two ends of the protective cover and the piston rod respectively so that the piston rod can have elastic restoring force in the direction opposite to the movement direction.
本发明属于土木工程结构减震技术领域，涉及一种齿轮齿条式自复位电涡流阻尼器，包括保护罩、至少一组永磁体、活塞杆、齿轮、导体转盘以及受压弹簧，所述永磁体分别设置在保护罩中的上下两侧以在所述保护罩中形成磁场，所述活塞杆插入保护罩中与转动安装在保护罩中的齿轮啮合，且所述活塞杆与保护罩活动连接以使得活塞杆能够沿其自身轴向运动，并在活塞杆远离保护罩的一端设有用于连接外部受控结构的活塞杆连接件；所述导体转盘固定连接在齿轮上以跟随齿轮转动，并切割磁感线以形成电涡流阻尼效应，且所述导体转盘的尺寸至少为所述齿轮的尺寸的10倍；受压弹簧为两个，并分别安装于保护罩的两端与活塞杆之间，以使得活塞杆具有与运动相反方向的弹性恢复力。
