| Summary: | With the trend of lighter vehicle and more powerful engine (power plant) passengers are subjected to large vibration and harshness coming from the engine through the chassis. This paper discusses the application of active vibration control to reduce this vibration effect. Using a mass-spring-damper model which represents a passive engine mount, dynamic characteristic of the mount is obtained for both lower frequency level (< 20 Hz) and higher frequency level (> 20 Hz.). Based on this characteristic an ideal vibration isolation model is deduced and it has been found that it is frequency dependent. Feedback control system strategy is presented and simulated using MatLab to see the amplitude comparison between passive engine mount and active engine mount. The active vibration control strategies show good improvement in reducing the vibration effect from the power plant to the chassis of the vehicle and thus to the passenger. |
