Abstract
A magnetic fluid damper includes a housing defining a cavity; a plurality of mass blocks located in the cavity and spaced from each other in a first direction; at least one energy dissipating assembly, in which the plurality of mass blocks and the at least one energy dissipating assembly are arranged alternately along the first direction in the cavity, in which each energy dissipating assembly includes a first permanent magnet and a first porous medium member, pores of each first porous medium member being filled with first magnetic fluid; and a plurality of reset parts cooperating with the plurality of mass blocks in one-to-one correspondence to apply restoring forces in a second direction to the mass blocks, in which restoring forces received by two mass blocks adjacent in the first direction are not equal.
