Abstract

Abstract:

A hydraulically interconnected suspension system with dual accumulators （DHIS） is proposed to improve vehicle dynamic performance. The model for DHIS system is established according to its structure characteristics and then the entire vehicle model including the proposed model is derived and verified with experimental results under sine-wave maneuver. The whole vehicle models installed respectively with hydraulically interconnected suspension with dual accumulators， single accumulator and the original mechanical suspension system are simulated under different motion modes， the influence of which on the stiffness and damping characteristics of the DHIS system， hydraulically interconnected suspension （HIS） system and the original mechanical suspension system on the vehicle model is compared and analyzed， followed by the vehicle performance analyses for the three types of suspension system in both time- and frequency- domains. Simulation results show that the roll stiffness and roll-damping coefficient are significantly enhanced with DHIS system， but those in pitch and bounce motion modes slightly affected. Under sine-wave steering， the roll angle， roll rate and suspension deflection are decreased effectively with DHIS system， which hence enhance vehicle handling performance； and under the condition of random road surface， the ride comfort is slightly affected， and the tire-road friendliness can be effectively improved.
