magnetorheolog ical shock absorber semiactive cont rol vibration isolat ion
This paper takes suspension system as an ex ample to evaluate the v ibration isolation characterist ics of the semiact ively cont rolled system w hich adopts magnetorheolog ical shock absorber. Compared w ith the convent ional passive dampers, the semiact ive dampers are able to isolate at lower f requencies, and they also do not add any energy to the system. The result s show that for suff icient ly large damping rat io, semiactive dampers are able to provide isolat ion at all frequencies and mag netorheological shock absorber is a promising controllable vibration isolation unit .
