Ride Performance Analysis of a Semi-active Hydraulic Engine Mounting System of a Passenger Car

To enhance a passenger car ride comfort, a semi-active hydraulic engine mounts (HEMs) is offered to analyze the ride comfort performance of its compared to passive hydraulic engine mounts (HEMs). A FLC (Fuzzy Logic Controller) is set up a damping coefficient control of a semi-active HEMs. The obtained results show that the peak amplitude acceleration response values of vehicle body with semi-active HEMs respectively reduce compared to passive HEMs under the survey conditions. Especially, the root mean square (r.m.s) acceleration response values of vehicle body (awb, awphi and awteta) with semi-active HEMs respectively reduce by 14.7%, 8.40% and 8.81% respectively compared to passive HEMs when the vehicle operates under survey conditions.
