Zusammenfassung:The present invention relates to a semi-active engine mount for a vehicle capable of improving noise, vibration, and harshness (NVH) performance and ride comfort by lowering a mount dynamic characteristic when idling, and increasing a loss coefficient when driving. The present invention is able to not only secure NVH performance and excellent ride comfort by lowering dynamic characteristics during idle and increasing a loss coefficient when running, but is also able to obtain a high loss coefficient under a prompt driving condition and the like. The present invention is able to not only improve all the idle vibration as well as driving vibration, which can lower dynamic characteristics under the condition of idle, but also is particularly able to minimize costs and weight increase by reducing the number of parts and simplifying a structure. In addition, the present invention is advantageous in terms of package by having the same size as an existing hydro mount. The present invention comprises a rubber module (13), a fluid module (21), and a coil module (23). 본 발명은 공회전 시 마운트 동특성을 낮추고 주행 시 손실계수를 높여 NVH 성능과 승차감을 향상시킬 수 있는 차량용 세미 액티브 엔진 마운트에 관한 것이다. 본 발명은 공회전 시에는 동특성을 낮추고 주행 시에는 손실계수를 높여 NVH 성능과 우수한 승차감을 확보할 수 있음은 물론, 즉 주행 시 등의 조건에서 높은 손실계수를 얻을 수 있고, 공회전 시 등의 조건에서 동특성을 낮출 수 있는 등 주행 진동은 물론 공회전 진동을 모두 개선할 수 있음은 물론, 특히 부품 수 삭제 및 구조 단순화를 통해 원가 및 중량 상승을 최소화하고, 기존 하이드로 마운트와 사이즈가 동일하여 패키지 측면에서 유리한 차량용 세미 액티브 엔진 마운트를 제공한다.
