Lever bridge type mixed two-stage amplification damper
The invention provides a lever bridge type mixed two-stage amplification damper which comprises a restraining device, lever bridge type mixed amplification devices are symmetrically arranged in the front end and the rear end of the restraining device, a damper is connected between the two lever bridge type mixed amplification devices, and each lever bridge type mixed amplification device comprises a loading control. The outer end of the loading control is located outside the restraining device, lever amplifying devices are symmetrically connected to the left side and the right side of the inner end of the loading control respectively, each lever amplifying device is provided with a fixed pin shaft, a first movable pin shaft and a second movable pin shaft which are arranged in a triangular mode, the fixed pin shafts are hinged to the restraining device, and the second movable pin shafts are hinged to sliding long holes in the inner end of the loading control. The first movable pin shaft is hinged to one end of a rotating plate, and the other end of the rotating plate is hinged to a damper. A lever and bridge type mixed amplification mechanism is adopted, the displacement amplification function of the damper can be effectively improved, and the damper is suitable for external excitation under the low-intensity effect.
本发明提供一种杠杆桥式混合二级放大阻尼器，包括约束装置，约束装置的前后两端内对称设置有杠杆桥式混合放大装置，两个杠杆桥式混合放大装置之间连接有阻尼器，杠杆桥式混合放大装置包括加载控件，加载控件的外端位于约束装置外，内端的左右两侧分别对称连接有杠杆放大装置，杠杆放大装置具有呈三角形排布的固定销轴、第一活动销轴和第二活动销轴，固定销轴与约束装置铰接，第二活动销轴与加载控件的内端处的滑动长孔铰接，第一活动销轴与转动板的一端铰接，转动板的另一端与阻尼器铰接。本发明采用杠杆和桥式混合放大机构，可有效提升阻尼器的位移放大功能，适用于低强度作用下的外部激励。
