Recent trends in lighter and smaller vehicles have motivated the application of adaptive hydraulic engine mounts for control of vehicle frame vibrations. This paper presents the results of a study on hydraulic engine mounts implemented on a light truck. The focus is on derivation of an optimal scheme for tuning the adaptive mounts. A simplified model of a vehicle engine suspension systems is derived. Simulations of receptance and accelerance are conducted to provide insight into mount tuning. An optimal mount tuning function is derived based on maximization of kinetic energy in the bleed fluid loop. Peak accelerance is attenuated by 18 db concurrently with peak receptance attenuation of 6 db. A general scheme for formulation of the tuning is presented.
