Adjustable electromagnetic damping type tuned mass-inertial mass damper
The invention discloses an adjustable electromagnetic damping type tuned mass-inertial mass damper, and belongs to the technical field of dampers. The damper comprises a ball screw mechanism, a fixingbase, polished shafts, a coupler, a motor, mass blocks, springs and an external connecting frame, the external connecting frame is used for being connected to an external structure and serves as a supporting base for a damper body, the upper end of a lead screw of the ball screw mechanism penetrates through the fixing base, the lower end of the lead screw is connected to the motor through the coupler, a ball nut is arranged on the inner side of the fixing base and is connected to the lead screw, the mass blocks and the springs are arranged on the outer side of the lead screw and penetrate through the polished shafts, the external connecting frame is connected to an external vibration structure, and the mass blocks are driven by external vibration to do linear motion along the polished shafts so as to enable linear motion of the ball nut in a center empty groove to be converted into rotating motion of the lead screw. According to the damper, energy generated by vibration of the external vibration structure can be converted into motion kinetic energy of the mass blocks and electric energy of the motor to be greatly consumed, and therefore the vibration reduction/shock absorption effect can be achieved.
本发明公开了一种可调电磁阻尼的调谐质量‑惯质阻尼器，属于阻尼器技术领域。包括滚珠丝杠机构、固定座、光轴、联轴器、电机、质量块、弹簧和对外连接架，所述对外连接架用于连接外部结构并且是阻尼器的支承座；所述滚珠丝杠机构的丝杠上端穿过固定座，下端通过联轴器连接所述电机，滚珠螺母安装在固定座内侧且与丝杠连接；所述质量块和弹簧均安装在丝杠外侧且均穿过光轴，对外连接架连接外部振动结构，质量块在外部振动的带动下沿光轴做直线运动以使滚珠螺母在所述中心空槽中做的直线运动转化为丝杠的旋转运动。本发明可将外部振动结构振动产生的能量转化为质量块的运动动能和电机的电能而大量消耗掉，因此能起到减振/减震的效果。
