The invention provides a magneto-rheological buffer which comprises a magneto-rheological damper, an elastic component, a first connecting component, a second connecting component and a third connecting component. The two ends of the magneto-rheological damper are connected with the first connecting component and the second connecting component in a detachable manner, the elastic component is located between the second connecting component and the magneto-rheological damper, and the third connecting component is arranged at the end, far away from the magneto-rheological damper, of the second connecting component in the detachable manner. The elastic component has a pre-compression amount enabling the magneto-rheological damper to reset. The first connecting component is connected with themotion end, and the third connecting component is connected with the fixed end. Dual adjustment of the damping force and the rigidity can be achieved, and the response speed is high.
Description
technical field [0001] The invention relates to the technical field of vibration reduction, in particular to a magneto-rheological buffer. Background technique [0002] The buffer is a mechanical device widely used in high-strength impact environments to reduce the over-shock of the structure and avoid the resonance problem of the structure. The existing hydraulic shock absorber belongs to the passive control mode, the characteristics are fixed and cannot be adjusted, and the response speed is slow, which cannot meet the response time requirements in the case of high-speed reciprocating impact motion. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a magneto-rheological buffer, which can realize dual adjustment of damping force and stiffness, and has a fast response speed. [0004] In order to solve the problems of the technologies described above, the technical so...
