Abstract
The authors have developed a new type of active engine mount. The active engine mount is consisted of an electromagnetic actuator and an inertia-modulator hydraulic mount. The decoupler's motion is controlled by the dynamic force generated by the electromagnetic actuator .The pressure in the upper chamber is variational, as a result the total output force from the mount to the chassis is controlled. Fuzzy control method was chosen as the control method. Based on force analyses of system parts, a mathematical model of the active engine mount was established. An experimental device was designed and made. The experimental results indicated that the active engine mount can achieve better vibration isolation performance than passive engine mount.
