Document Type and Number:
WIPO Patent Application WO/2021/143245
Kind Code:
A1
Abstract:
A magnetorheological fluid particle impact damper, comprising a damper cavity unit (2). An electromagnetic coil (1) is provided in the circumferential direction of the damper cavity unit (2), several horizontal shock absorbers are uniformly provided inside, and disc-type shock absorbers are symmetrically provided at the left end and the right end of the damper cavity unit; the horizontal shock absorbers and the disc-type shock absorbers are separately connected to the inner wall of the damper cavity unit (2) by means of springs; each horizontal shock absorber comprises a horizontal magnetorheological fluid cavity (5) filled with a magnetorheological fluid; a horizontal impactor container (6) is provided in each horizontal magnetorheological fluid cavity (5); a first impactor group is provided in each horizontal impactor container (6); the first impactor group consists of several impactors having different sizes; the disc-type shock absorber comprises a disc-type magnetorheological fluid cavity (18) filled with the magnetorheological fluid; the disc-type magnetorheological fluid cavity (18) is slidably connected to several disc-type impactor containers (19); the disc-type impactor containers (19) are distributed in a circumference array; a second impactor group is provided in the disc-type impactor containers (19). A vibration reduction effect is improved.
