Meanwhile, the second sliding part 8 drives the second free baffle 2-2 to move rightwards, and the elastic shock absorption part 4 on the right side is pressed to generate elastic-plastic deformation, so that the vibration energy is absorbed and consumed. In the process, the elastic restoring elements 3 are stretched in tension. When the first position-limiting element 7-3 of the first sliding element 7 is in contact with the first end plate 5 and the third position-limiting element 8-5 of the second sliding element 8 is in contact with the second end plate 6, the displacement of the first sliding element 7 and the second sliding element 8 is limited.

As shown in fig. 3, when the dissipative vibration damping damper is compressed, the first sliding member 7 pushes the second free barrier 2-2 to move rightwards, and the right elastic damping member 4 is compressed to deform elastically and plastically, thereby absorbing the consumed vibration energy. Meanwhile, the second sliding part 8 pushes the first free baffle 2-1 to move leftwards, and the elastic shock absorption part 4 on the left side is pressed to generate elastic-plastic deformation, so that shock energy is absorbed and consumed. In the process, the elastic restoring elements 3 are stretched in tension. When the second free baffle 2-2 is in contact with the limiting plate 8-2 of the second slider 8, the displacement of the first slider 7 and the second slider 8 is limited, and meanwhile, the second limiting part 7-4 and the fourth limiting part 8-6 play a role in auxiliary limiting, so that the two ends of the damper can uniformly displace, and one end of the damper is prevented from being excessively displaced.
Then, when the pressure of the energy consumption damping damper is unloaded, the first free baffle 2-1 and the second free baffle 2-2 are automatically reset under the action of the elastic restoring force of each elastic resetting piece 3, so that the two elastic damping pieces 4 are driven to realize automatic resetting, and the energy consumption damping damper is reset to the initial state shown in fig. 1.
