Problems solved by technology

Common dampers often only have one-way damping and vibration reduction capabilities. When subjected to loads in other directions, the application of one-way dampers will be limited. It is necessary to form a platform to meet the multi-directional damping and vibration reduction requirements.

Embodiment Construction

[0030] The present invention provides a three-way viscoelastic damper, such as figure 1 As shown, it includes: upper damping layer 1, lower damping layer 2, ball head mandrel 3, shell 4 and ball seat 5;

[0031] One end of the ball head mandrel 3 is an external thread, and the other end is a ball head; the shell 4 is a hollow rotating body, and the inside is a spherical surface and a cylindrical surface, and the top of one end of the spherical surface has a through hole, and one end of the cylindrical surface is an internal thread;

[0032] The upper damping layer 1 is in the shape of a hemispherical shell with a central hole on the top, the outer surface of the upper damping layer 1 is bonded to the inner spherical surface of the shell 4, and the inner surface of the upper damping layer 1 is bonded to the ball head of the ball head mandrel 3;

[0033] The lower damping layer 2 is in the shape of a hemispherical shell and its outer surface is bonded to the inner surface of the...

Abstract

The invention discloses a three-way viscoelastic damper, which mainly comprises a ball head spindle, a ball seat, a shell and a damping layer and the like. Through relative motion of a ball head, the ball seat and the shell, viscoelastic materials are subjected to shear deformation, so that the mechanical vibration energy is dissipated, and a damping aim is fulfilled. By the three-way viscoelastic damper, three-way damping can be realized, and the three-way viscoelastic damper has the advantages of simple structure, convenience in assembly, wide application range and the like.

Description

technical field [0001] The invention relates to a three-way viscoelastic damper, which belongs to the technical field of damping and vibration reduction. Background technique [0002] At present, damping vibration reduction technology is widely used in machinery, construction, aerospace and other fields. Common dampers often only have one-way damping and vibration reduction capabilities. When subjected to loads in other directions, the application of one-way dampers will be limited. It is necessary to form a platform to meet the multi-directional damping and vibration reduction requirements. In actual engineering, the application range of multi-directional dampers is wider. Viscoelastic material is a commonly used damping material, which can dissipate vibration energy by its own deformation, and has good damping and vibration reduction performance. Compared with tension and compression deformation, viscoelastic materials have a stronger energy dissipation capacity when she...
