Research on Semi-active Control of Engine Vibration Basing on Electro-Rheological(ER) Technology

摘要

According to the demand of engine mount, using ER technology to research on the active engine vibration isolation. Introduced ER technology and ER mount in detail. Established the model of active engine vibration isolation. Designed the self-adjusting parameters' fuzzy controller, which maked the performance of fuzzy controller in high-point. Then used MATLAB software to simulate and analyse the model. The results show that the fuzzy control is more effective than the passive control. Especially, in the range of low frequency vibration, and makes a progress in engine vibration isolation and noise reducing.
