승용차용 기존 엔진마운트와 ER 엔진마운트의 성능비교

초록

This paper presents vibration suppression of conventional and ER engine mounts for passenger vehicles. After devising a mixed-mode ER engine mount, a sky-hook controller is designed to reduce unwanted vibration. Vibration control characteristics of the proposed ER engine mount and conventional mounts are analyzed by consideringn engine excitation. RMS displacement at the center of gravity and RMS transmitted forces are presented and compared.
