Abstract/Summary In this paper, the development of a hydraulically interconnected suspension (HIS) system model and its integration into a four degree-of-freedom half-car system is briefly introduced. Frequency response functions are derived in order to simulate the system response to a stochastic road profile. The sprung mass vertical and roll accelerations are considered in the frequency domain up to 1000 Hz. Four key hydraulic system parameters which affect the system’s high frequency dynamics but not its low frequency response are identified and investigated. The results indicate that HIS system performance in the high frequency range (50-1000 Hz) can be greatly affected by these hydraulic parameters, while the favourable ride characteristics typical of HIS vehicles are retained.
