Abstract:
In this paper, the development of a hydraulically interconnected suspension
(HIS) system model and the integration of this model into a four degree-of-freedom half-car
system is briefly introduced. The appropriate frequency response functions are derived in
order to simulate the system response to a stochastic road profile. The sprung mass vertical
and roll accelerations, the dynamic normal tyre force, and the suspension deflection are
considered in the frequency domain up to 20 Hz. The simulated responses of two equivalent
half-car models with conventional independent suspensions are also provided for comparison.
The results indicate that HIS systems provide a potentially viable method by which to
partially overcome the ride/handling compromise.
