On the trade-off performance curve of vibration isolation controlled by passive or adaptive dampings

This paper addresses an on-off adaptive damping isolation, in which the can be frequency dependent. The comparison with passive isolation is illustrated by trade off performance curve, shown relation between displacement and force transmissibility. control based on dampings a switching frequency. analytical optimization of law obtained. optimized showed remarkable improvement comparing one. At last, self-made magnetorheological fluid introduced to show capability provide variable damping.
