Novel plate type double-step sliding friction damping energy dissipation device
The invention relates to the technical field of building damping, in particular to a novel plate type double-step sliding friction damping energy dissipation device. Comprising a first-order friction unit and a second-order friction unit which are connected in series, each of the first-order friction unit and the second-order friction unit is formed by laminating a pressing plate, a friction material and a friction steel plate, and the first-order friction unit and the second-order friction unit share the same pressing plate; a sinking groove is formed in a friction steel plate of a first-order friction unit, stop blocks are additionally arranged on pressing plates on the two sides of the first-order friction unit to form a limiting device, after the first-order friction unit consumes energy under certain displacement, the second-order friction unit consumes energy, and the friction coefficient of a friction material of the first-order friction unit is smaller than that of a friction material of the second-order friction unit. Friction energy dissipation can be achieved under both small earthquakes and large earthquakes, the first-order friction force and the second-order friction force can be adjusted, and meanwhile the double-order sliding friction damping energy dissipation device is simple in structure, convenient to maintain and replace and large in sliding stroke and has excellent energy dissipation and shock absorption capacity.
本发明涉及建筑减震技术领域，尤其涉及一种新型板式双阶起滑摩擦阻尼消能器；包括相互串联的一阶摩擦单元和二阶摩擦单元，所述的一阶摩擦单元和二阶摩擦单元由压板、摩擦材料及摩擦钢板叠层排布组成，所述的一阶摩擦单元与二阶摩擦单元共用同一块压板，通过在一阶摩擦单元的摩擦钢板开设沉槽和两侧压板增设档块形成限位装置，使一阶摩擦单元在一定位移下耗能后进行二阶摩擦单元耗能，所述的一阶摩擦单元的摩擦材料的摩擦系数小于二阶摩擦单元的摩擦材料的摩擦系数；本发明在小震及大震下均能实现摩擦耗能，且一阶摩擦力和二阶摩擦力均可调节，同时，该双阶起滑摩擦阻尼消能器结构简单，维修更换方便，滑动行程较大，具有优越的耗能减震能力。
