#$%^&*AU2020100594A420200528.pdf#####Abstract The invention discloses a magnetorheological fluid particle collision damper, which comprises a damper cavity unit. The damper cavity unit is provided with an electromagnetic coil in the circumferential direction, a plurality of horizontal shock absorbers are evenly arranged inside, and a disc-type shock absorber symmetrically arranged at the left and right ends.The horizontal shock absorber and the disc-type shock absorber are respectively connected to the inner wall of the damper cavity unit through a spring; the horizontal shock absorber includes a horizontal magnetorheological fluid cavity filled with a magnetorheological fluid. A horizontal impactor container is arranged in the horizontal magnetorheological fluid cavity. A first impactor group is arranged in the horizontal impactor container, and the first impactor group is composed of several impactors of different sizes; the disc-type shock absorber includes a disc-type magnetorheological fluid cavity filled with a magnetorheological fluid; the disc-type magnetorheological fluid cavity is slidably connected with a plurality of disc-type impactor containers, and the disc-type impactor containers are distributed in a circular array. The disc-type impactor container is provided with a second impactor group; the invention effectively improves the vibration reduction effect.
