Abstract
The similar model is made to three-layer building structure, the 4-DOF vibration system is built up; the parameter of MRF
absorber is optimized and designed, the mass, damping coefficient and rigidity are obtained according to the characteristic of
structure; a set of testing system of semi-active vibration control is designed to study the effect of MRF damper, considering
the natural frequency and strength of external magnetic field, the amplitude of structure can be decreased obviously after
using MRF absorber and the vibrating process is stabilized, validating the effect on shock absorber of MRF absorber..
