능동형 공압 엔진마운트 시스템의 모델링 및 동특성 해석

This study presents the modeling and the simulation results of the PAEM(Pneumatic Active Engine Mount) to minimize the excited vibration induced by a engine. The control parameters of PAEM system are duty ratio and time delay of PWM signal into the solenoid valve associated with vacuum tank pressure. These three parameters should be turned with different impact frequencies for PAEM to be operated optimally. Consequently, in this study, by using constructed equivalent model of PAEM, the computer simulation is implemented to determine the best values of duty ratio, time delay and vacuum tank pressure.
