The Development of Hydraulic Strut Mount

This paper describes the development of a high performance hydraulic strut mount, which has low complex stiffness at high frequency range. To improve vehicle noise and vibration, the dynamic characteristics of the hydraulic mount were enhanced. A hydraulic chamber model was applied in the design of the strut mount which has low complex stiffness at high frequency range. A high performance hydraulic strut mount with the inner orifice is designed by applying the result of the analysis of a hydraulic chamber model and experimentally measured data. A well designed hydraulic strut mount reduces road noise for front wheel drive car.
