The invention discloses a displacement self-adaptive staged ring rotating viscous damper which comprises an outer cylinder, one end of the outer cylinder is fixedly connected with a first connecting lug ring, and the other end of the outer cylinder is provided with a second connecting lug ring. By controlling the length of the threaded part of the threaded transmission rod and the distance between the transmission rod nuts, the multiple transmission rod nuts are controlled to work at the same time in sequence, and displacement self-adaption staged control over an engineering structure under the earthquake effect is achieved. When the vibration displacement generated by the structure is small, the damper only starts one transmission rod nut to work, the small energy consumption requirement of the structure is met, when the vibration displacement of the structure is increased, the damper further starts the two transmission rod nuts to work at the same time, generated damping is larger, the energy consumption capacity is higher, and the large energy consumption requirement of the structure is met. Furthermore, the distance between the threaded part of the threaded transmission rod and the transmission rod nuts and the number of the transmission rod nuts are reasonably set, and the displacement self-adaption multi-stage control energy dissipation and shock absorption effect can be achieved.
本发明公开了一种位移自适应分阶段环转粘滞阻尼器，包括外筒，所述外筒的一端固定连接有第一连接耳环，所述外筒的另外一端设有第二连接耳环。本发明中通过控制螺纹传动杆有螺纹部分的长度和传动杆螺母之间的距离，控制多个传动杆螺母先后同时工作，实现了对工程结构在地震作用下的位移自适应分阶段控制。当结构产生的振动位移较小时，阻尼器只启动一个传动杆螺母工作，满足结构较小的耗能需求，当结构的振动位移增大，阻尼器进而启动两个传动杆螺母同时工作，产生的阻尼更大，耗能能力更强，满足结构较大耗能需求；进一步地，合理地设置螺纹传动杆的螺纹部分与传动杆螺母的间距和传动杆螺母的数量，可实现位移自适应分多阶段控制耗能减震效果。
