Compact damper with self-resetting function
The invention discloses a compact damper with a self-resetting function, and relates to the technical field of bridge structure vibration reduction control. The compact damper comprises a cylinder barrel, a baffle is arranged at one end of the cylinder barrel, and an opening is formed in the other end of the cylinder barrel; the guide rod is arranged on the baffle and located in the cylinder barrel; the piston is movably arranged on the guide rod in a surrounding mode, and the outer wall of the piston abuts against the inner wall of the cylinder barrel; one end of the piston rod is arranged on the piston, the other end of the piston rod is located outside the opening, a groove is formed in the end, close to the piston, of the piston rod, one end of the guide rod is located in the groove, and the compact damper is provided with a first containing space and a second containing space. According to the invention, the volume change of the first accommodating space is larger than or smaller than the volume change of the second accommodating space, when the total volume is reduced, the amount of the damping medium is not changed, so that the damping medium in the first accommodating space or the second accommodating space is compressed, and a force for resetting the piston rod is generated.
本发明公开了一种具有自复位功能的紧凑型阻尼器，涉及桥梁结构减振控制技术领域。该紧凑型阻尼器包括缸筒，其一端设置有挡板，其另一端为开口；导杆，其设置于挡板上，且位于缸筒的内部；活塞，其可移动地环绕设置于导杆上，且其外壁与缸筒的内壁相抵；活塞杆，其一端设置于活塞上，活塞杆的另一端位于开口外部，活塞杆靠近活塞的一端开设有槽，导杆的一端位于槽的内部，该紧凑型阻尼器具有第一收容空间和第二收容空间。本发明根据第一收容空间的体积变化大于或小于第二收容空间的体积变化，当总体积为减小时，但阻尼介质的量是不变的，导致第一收容空间或第二收容空间内的阻尼介质进行了压缩，从而产生一个使活塞杆复位的力。
