Curved-surface flow channel viscous damper
The invention discloses a curved-surface flow channel viscous damper. The viscous damper comprises a right pin head, an auxiliary end, an auxiliary cylinder barrel, a right end cover, a cylinder barrel, a right piston rod, a piston, a left end cover, a left piston rod, a left pin head, a left piston rod one-way valve, a piston rod middle body, a left working valve element, a spring, a right working valve element, a right piston rod one-way valve, an oil plug and an anti-loosening limiting pin. According to the viscous damper, specific curved surfaces are arranged on the working valve elementsof the viscous damper, and through the combined action of valve element movement and curved surface characteristics, the rising rate of the vibration load caused by increase of the vibration speed iseffectively controlled, a viscous damper load F-speed V target relation curve is achieved, vibration energy is effectively absorbed, the safety of a building is fully protected, and the application prospects are wide.
本发明公开了一种曲面流道粘滞阻尼器，包括右销头、辅助端头、辅助缸筒、右端盖、缸筒、右活塞杆、活塞、左端盖、左活塞杆、左销头、左活塞杆单向阀、活塞杆中间体、左工作阀芯、弹簧、右工作阀芯、右活塞杆单向阀、油堵和防松限位销。本发明提出，在粘滞阻尼器的工作阀芯上设置特定曲面，通过阀芯移动和曲面特性的联合作用，有效控制振动速度增加引起的振动载荷的上升速率，实现粘滞阻尼器载荷F‑速度V目标关系曲线，有效吸收振动能量，充分保护建筑物的安全，具有广泛的应用前景。
