Adjustable variable-damping variable-inertia mass damper
The invention particularly provides an adjustable variable-damping variable-inertia mass damper. The damper comprises a ball screw device which comprises a ball screw and a ball nut arranged on the outer side of the ball screw in a sleeving mode. The upper portion of the ball nut is connected with a variable damping device. The variable damping device comprises a lead screw guide cylinder, a plurality of magnetic steels, a copper pipe and a lead screw guide cylinder jacket, the magnetic steels are uniformly arranged in the copper pipe in the radial direction and located on the outer side of the lead screw guide cylinder, the copper pipe is arranged on the outer side of the lead screw guide cylinder in a sleeving manner, the lead screw guide cylinder jacket is arranged on the outer side of the copper pipe in a sleeving manner, the lower part of the lead screw guide cylinder is connected with a ball nut, and the upper part of the lead screw guide cylinder is connected with the variable inertia mass device; the variable inertia mass device comprises a hysteresis clutch, the output end of the hysteresis clutch is connected with the rotating flywheel through a coupler, and the input end of the hysteresis clutch is connected with the upper portion of the lead screw guide cylinder. Torque generated by the ball screw device is transmitted to the variable damping device, the rotating speed of the screw guide cylinder is slowed down through the variable damping device, and the total inertia mass of the damper is changed through the variable inertia mass device.
本发明具体提供一种可调式变阻尼变惯性质量阻尼器。本发明的阻尼器包括滚珠丝杆装置包括滚珠螺杆、套设于滚珠螺杆外侧的滚珠螺帽，滚珠螺帽的上部连接有变阻尼装置；变阻尼装置包括丝杆导筒、径向均匀布置于铜管内且位于丝杆导筒外侧上的多个磁钢、套设于丝杆导筒外侧的铜管、套设于铜管外侧的丝杆导筒外套，丝杆导筒的下部与滚珠螺帽连接，丝杆导筒的上部与变惯性质量装置连接；变惯性质量装置包括磁滞离合器，磁滞离合器的输出端通过联轴器与旋转飞轮连接，磁滞离合器的输入端与丝杆导筒的上部连接。实现了将滚珠丝杆装置所产生的扭矩传递至变阻尼装置，再通过变阻尼装置减慢丝杆导筒的旋转速度，并通过变惯性质量装置改变阻尼器的总惯性质量。
