Analysis of Damping Components of Roll Resistant Specific Hydraulically Interconnected Suspension System

Abstract

This paper presents a full-car model of vehicle fitted with roll resistant specific HIS system in order to research the coordination of the main modals of sprung mass. Based on the transfer matrix method and state space method, the mechanical and hydraulic coupled multi-body dynamic equation is derived. The eigenvalue and eigenvector is solved by eigenvalue iteration identification method of frequency-dependent characteristic. By discussing the characteristic of the damping components which are the dominant parameters of the coupled system, an innovative design approach of damping components of the HIS system is proposed. Finally, comparison of vehicle vibration is carried out between vehicle with traditional suspension and that fitted with roll resistant specific HIS system. The obtained result indicates that with the proposed design approach of damping components, the roll resistant specific HIS system can promote the capacity of anti-rollover specific observably with reasonable comfort performance.
