Drawings
FIG. 1 is a schematic view of a viscoelastic damper of the present invention.
In the above drawings: 1. a connecting plate; 2. a lever; 3. a rigid plate; 4. a curved viscoelastic damping layer; 5. a planar sheet member; 6. a planar viscoelastic damping layer.
Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings to which the invention is attached.
The first embodiment is as follows: as shown in fig. 1, a viscoelastic damper includes a pair of connection plates 1 and a damping module. A pair of connecting plates 1 are arranged in parallel relatively and have a certain distance, and a damping module is connected between the pair of connecting plates 1.
The damping module at least comprises a plurality of rigid plates 3 which are arranged in a stacked mode and a viscoelastic damping layer formed by viscoelastic materials filled between two adjacent rigid plates 3. The two opposite surfaces with the largest area of the rigid plate 3 are curved surfaces, so that the surface with the largest area of the viscoelastic damping layer is also in a curved surface state, and the curved surface type viscoelastic damping layer 4 is formed.
The damping module may be entirely composed of the rigid plate 3 and the curved viscoelastic damping layer 4. In the present embodiment, the longitudinal section of the rigid plate member 3 is S-shaped, and includes three parallel portions and an arc portion connecting adjacent two parallel portions. When the rigid plate members 3 are stacked, the sizes of the arc-shaped portions thereof are different, thereby constituting the damper module in a solid state.
In the damping module, the scheme may also be: the rigid plate 3 is laminated to form a groove, a plurality of flat plate parts 5 are laminated in the groove, and a viscoelastic material is filled between the adjacent flat plate parts 5 to form a planar viscoelastic damping layer 6. The planar plate members 5 are arranged laterally and/or longitudinally to completely fill the grooves formed by the stacking of the rigid plate members 3 to form the damping module in a solid state. In this embodiment, a plurality of planar plate members 5 are transversely disposed in the grooves formed in the rigid plate 3, i.e., the planar plate members 5 are disposed in parallel with the parallel portions of the rigid plate 3, and are provided with respective planar viscoelastic damping layers 6. The lengths of the planar plate members 5 are slightly different to enable them to fit the rigid plate member 3. The planar viscoelastic damping layer 6 is connected only to the surface of the planar plate member 5 having the largest area.
In the scheme, the connecting plate 1, the rigid plate 3 and the flat plate 5 are all steel plates, the thickness of the connecting plate 1 is the largest, and the thickness of the flat plate 5 is the smallest.
In the above scheme, the connecting plate 1 is connected with the outermost rigid plate 3 in the damping module through a plurality of rotatable levers 2. The distance between the rotating axis of the lever 2 and the connecting plate 1 is smaller than the distance between the rotating axis of the lever 2 and the rigid plate 3 at the outermost side, so that the displacement can be amplified, and energy consumption can be better realized. The position of the rotating axis of the lever 2 is set according to the required displacement amplification ratio, and the multiple of the distance between the rotating axis of the lever 2 and the outermost rigid plate 3 and the distance between the rotating axis of the lever 2 and the connecting plate 1 is the displacement amplification multiple, for example, the distance between the rotating axis of the lever 2 and the outermost rigid plate 3 is set to be three times the distance between the rotating axis of the lever 2 and the connecting plate 1.
When the shock absorber is vibrated, the connecting plate 1 is relatively displaced, so that energy is consumed by mutual shearing between the rigid plate 3 and the curved surface type viscoelastic damping layer 4 and between the plane plate 5 and the plane type viscoelastic damping layer 6, and the action area is increased by the curved surface design, so that the damping effect can be improved.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
