“…The transmission mechanisms in lateral and torsional directions, namely bending and torsional waves, were considered by Schlesinger (1991a, 1991b). Longmore et al (1997) and Johnston et al (2007) presented several methods to obtain the dynamic material properties of flexible hoses used in all types of theoretical models. The hose properties were obtained by measuring the impedance characteristics relating to longitudinal waves.…”

Pressure changes in the liquid-filled fluid circuit of a hydraulically interconnected suspension (HIS) system can induce vibrations of the whole pipeline and the associated structure, and hence become a source of structural noise which degrades ride comfort. This paper presents a numerical and experimental investigation into the vibration of the hydraulic piping system of a passive interconnected suspension. The transfer matrix method (TMM) is used to develop a mathematical model, which consists of various pipe sections, hose sections, concentrated masses, spring supports, elbows, damper valves, and accumulators. Laboratory experiments are performed on two liquid-filled piping systems. The measured steady-state responses of the hydraulic circuits are compared with those obtained from numerical simulations of the developed model. It is found that the developed model of the hydraulic system has a reasonable accuracy in the frequency range of interest, and thus can be employed to optimise the design of the hydraulic system.
