本发明适用于减震抗震技术领域，提供了一种PALL摩擦耗能减震器，包括：第一导向杆，及垂直于第一导向杆设置的第二导向杆，设于第一导向杆和第二导向杆之间的位移放大装置，包括：交叉设置的受弯杆件a和受弯杆件b、以及交叉设置受弯杆件c和受弯杆件d，其中，受弯杆件a与受弯杆件b在交叉处与连接杆c铰接，受弯杆件c和受弯杆件d在交叉处与连接杆d铰接，受弯杆件a的一端和受弯杆件d的一端与连接杆b铰接，受弯杆件b的一端和受弯杆件c的一端与连接杆a铰接；以及用于连接受弯杆件间的四个摩擦耗能组件。该减震器在建筑结构发生较小位移条件下耗能减震器的摩擦耗能组件之间产生比较大的相对位移，从而消耗更多能量，获得更好的减震效果。

The invention is applicable to the technical field of shock absorption and resistance, and provides a PALL frictional energy dissipation damper. The PALL frictional energy dissipation damper comprisesa first guiding rod, a second guiding rod and a displacement amplifying device, wherein the second guiding rod is perpendicular to the first guiding rod, the displacement amplifying device is arranged on the position between the first guiding rod and the second guiding rod. The PALL frictional energy dissipation damper further comprises a flexural member a, a flexural member b, a flexural memberc and a flexural member d, wherein the flexural member a is arranged on the flexural member b in a crossed mode, the flexural member c is arranged on the flexural member d in a crossed mode, the intersection between the flexural member a and the flexural member b is connected with a connecting rod c in a hinged mode, the intersection between the flexural member c and the flexural member d is connected with a connecting rod d in a hinged mode, one end of the flexural member a and one end of the flexural member d are connected with a connecting rod b in a hinged mode, one end of the flexural member b and one end of the flexural member c are connected with a connecting rod a in a hinged mode. The PALL frictional energy dissipation damper further comprises four friction energy dissipation assemblies for connecting the flexural members. Relatively large relative displacement occurs between the friction energy dissipation assemblies of the energy dissipation damper under the condition of small displacement of a building structure, so that the more energy is consumed and the better damping effect is obtained.
