Frequency Response of a Base Excited System With Hydraulic Mount

This paper investigates the frequency response analysis of a hydraulic suspension system undergoing base excitation. The nonlinearity of the hydraulic suspension due to the decoupler action is taken into account and the effects of utilizing an inertia track in the design of the hydraulic mount are also considered. The analysis focuses on the development of the equations of motion for a three degree of freedom system, and the development of an appropriate model based on the equations of motion for the system, which is essential for utilization is an optimization procedure. The analysis was conducted using common numerical procedures such that the nonlinear effects of the model may be reasonably approximated.
