Disc type damper based on magneto-rheological elastomer and magneto-rheological fluid

Abstract

The invention relates to a disc type damper based on a magneto-rheological elastomer and magneto-rheological fluid. The disc type damper comprises a rotating shaft, a damper shell, a rotating disc, a coil and a damping assembly, wherein the rotating disc, the coil and the damping assembly are arranged in the damper shell. The damper shell is of a hollow disc type structure. The lower end of the rotating shaft sequentially penetrates shaft holes which are formed in the circle centers of the two surfaces of the damper shell and are in clearance fit with the rotating shaft. The rotating disc and the coil are sequentially arranged with the rotating shaft as the center from inside to outside. The rotating disc and the rotating shaft rotate jointly through a key. The damping assembly comprises the magneto-rheological elastomer and the magneto-rheological fluid, and the space, except for the rotating shaft, the rotating disc and the coil, in the damper shell is filled with the magneto-rheological elastomer and the magneto-rheological fluid. Compared with the prior art, the disc type damper has the beneficial effects of achieving dual damping, being good in effect, compact in structure and stable in rotating, facilitating wire leading and the like.

Description

technical field [0001] The invention relates to a magnetic fluid damper, in particular to a disc damper based on magnetorheological elastomer and magnetorheological fluid. Background technique [0002] Magnetically sensitive smart soft materials (also known as magnetorheological materials) are a type of multifunctional composite materials prepared by dispersing micron or nanoscale soft magnetic particles in different types of carriers. Due to their rheological properties can With continuous, rapid and reversible changes in the applied magnetic field, magnetically sensitive smart soft materials have been widely used and attracted more and more attention in the fields of construction, vibration control and automobile industry. According to the physical state and the type of matrix of magneto-sensitive smart soft materials under the condition of no external magnetic field, they can be roughly divided into magnetorheological fluids and magnetorheological elastomers. Magnetorheo...
