The arc-shaped energy-dissipating plate 5 is fixedly connected to the inner wall of the protective shell 4 by bolts, and the cylinder 2 is located in the middle of the arc-shaped energy-dissipating plate 5 and is arranged in close contact with the arc-shaped energy-dissipating plate 5, that is, a symmetrically arranged arc The sum of the thickness of the energy-dissipating plate 5 and the diameter of the cylinder 2 is equal to the inner distance of the protective shell 4 .

防护壳4包括平行设置的上防护壳8、下防护壳9以及与建筑结构件相连接的防护壳连接部10,如图3所示。上防护壳8和下防护壳9的两侧间均设有盖板11,如图4所示,且上防护壳8和下防护壳9间通过栓杆12连接固定。The protective shell 4 includes an upper protective shell 8 , a lower protective shell 9 arranged in parallel, and a protective shell connecting portion 10 connected with the building structure, as shown in FIG. 3 .

工作原理:在受到地震或风荷载横向水平力作用时,该阻尼器的滑动导杆3产生横向位移,滑动导杆3端部的圆柱体2跟随移动,对称设置于防护壳4内部的弧形耗能板5因与圆柱体2直接接触,从而会限制与减小滑动导杆3的进一步位移,而圆柱体2就会使得弧形耗能板5产生形变,利用其塑性弯曲变形达到消能减震的效果。设置于弧形耗能板5两端的弹簧用于提供给金属阻尼器的附加刚度,可调节弧形耗能板5的变形量,并且实现弧形耗能板5发生形变后的复位。Working principle: When subjected to the lateral horizontal force of earthquake or wind load, the sliding guide rod 3 of the damper produces a lateral displacement, and the cylinder 2 at the end of the sliding guide rod 3 moves accordingly, and is symmetrically arranged in the arc shape inside the protective shell 4 The energy dissipation plate 5 is in direct contact with the cylinder 2, which will limit and reduce the further displacement of the sliding guide rod 3, and the cylinder 2 will cause the arc-shaped energy dissipation plate 5 to deform, and use its plastic bending deformation to achieve energy dissipation Shock-absorbing effect. The springs arranged at both ends of the arc-shaped energy-dissipating plate 5 are used to provide additional stiffness to the metal damper, to adjust the deformation of the arc-shaped energy-dissipating plate 5 , and to realize the reset of the arc-shaped energy-dissipating plate 5 after deformation.
