Control of Engine Roll and Bounce Vibrations Using Hydraulic Mounts

抄録

A method for designing an engine mounting system using hydraulic insulators has been developed with the aim of controlling low-frequency engine vibrations in the roll and bounce modes. This method includes a design optimization theory for each hydraulic insulator and a procedure for determining the equivalent mass for various modes at the mount locations, and is applicable to integrated system optimization. Computer simulation results show that resonance peaks can be effectively reduced with a hydraulic engine mount system designed on the basis of this method.
