Displacement self-adaptive staged viscous damper with fusing mechanism
The invention discloses a displacement self-adaptive staged viscous damper with a fusing mechanism, which is characterized in that a shock insulation structure is arranged as a fusing device of the viscous damper, relative slippage of an upper structure and a lower structure is allowed within a designed displacement range, and a shock insulation effect is achieved; the damper body plays the roles of energy consumption and shock absorption after the displacement exceeds the designed displacement, the multiple rotary energy consumption units are controlled to work sequentially or simultaneously according to the displacement, when the displacement generated by vibration does not reach a fusing value, the damper body does not work, and when the displacement generated by vibration exceeds the fusing value, one rotary energy consumption unit is started, and the damper body does not work. When the displacement amount generated by vibration is continuously increased, the two rotating energy dissipation units are started to work at the same time, the energy dissipation requirement for strong vibration is met, displacement self-adaption multi-stage control over engineering structures such as bridges under the earthquake action is achieved, and the effect of prolonging the service life of the bridges is achieved.
本发明公开了一种具有熔断机制的位移自适应分阶段粘滞阻尼器，设置隔震结构作为粘滞阻尼器的熔断装置，在设计的位移量范围内允许上部构造和下部构造的相对滑移，达到隔震效果；在超过其设计的位移量后发挥耗能和减震的作用，并根据位移量控制多个旋转耗能单元先后或同时工作，当因震动产生的位移量未达到熔断值时，阻尼器本体不工作，当因震动产生的位移量超过熔断值时，启动一个旋转耗能单元，满足震动较弱的耗能需求，当因震动产生的位移量继续增大，启动两个旋转耗能单元同时工作，满足震动较强的耗能需求，实现对桥梁等工程结构在地震作用下的位移自适应多阶段控制，取得提高桥梁使用寿命的效果。
