This paper investigates the dynamic characteristics of an isolator supported by four air suspensions. Each air suspension has a cylinder, a reservoir tank and a slit restriction. The air suspension with the slit restriction provides damping which is introduced through the flow restriction connecting the cylinder and the reservoir tank. The slit restriction is effective for suppressing micro vibration because air flow in the restriction is viscous flow. The effects of the air suspension with the slit restriction are shown through theoretical analysis and experimental tests. An experimental investigation indicates the air suspension model including rubber membrane predicts frequency-domain behavior closely. Experimental tests show that the maximum transmissibility of the isolator is about 1.5 by choosing the optimal slit depth.
