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.
