Abstract

The invention discloses a passive compression type self-adaption vibration damper. The passive compression type self-adaption vibration damper comprises a shock excitation rod, first sliding blocks, first connection rods, second sliding blocks, second connection rods, a magneto-rheological elastic body, a permanent magnet, supports, a base, an upper clamp, a lower clamp, third connection rods, third sliding blocks and a spring. The top end of each second connection rod is connected with one end of the corresponding first connection rod through the corresponding second sliding block. The other ends of the first connection rods are connected with the shock excitation rod through the first sliding blocks. The bottom of the shock excitation rod is provided with the magneto-rheological elastic body. The bottom of each second connection rod is connected with one end of the corresponding third connection rod through the corresponding third sliding block. The lower clamp is arranged between the two third connection rods. The bottoms, in the base, of the second connection rods are provided with the supports. The upper clamp is arranged between the two second connection rods through the supports. The permanent magnet is arranged between the upper clamp and the lower clamp. The spring is arranged at the bottom of the lower clamp. The passive compression type self-adaption vibration damper achieves self-adaption vibration damping of a structure or a product and has the advantages of being simple in structure, small in size, convenient to use and relatively low in cost.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to a passive compression adaptive vibration reduction device. Background technique [0002] At present, with the advancement of science and technology, human beings have higher and higher requirements for vibration control of structures and products. Due to the potential advantages of good effect and strong adaptability, active vibration control technology has naturally become a high-tech in the field of vibration engineering. However, various existing shock absorbers, such as servo hydraulic shock absorbers and servo pneumatic shock absorbers etc., all have the disadvantages of large structure, heavy weight, and large driving power required, which limit their engineering applications. In recent years, the emergence and development of new intelligent materials provide a powerful tool for the design and development of new shock absorbers. [0003] Magnetorheological Ela...
