Abstract:

The fluid flow inside the liquid-filled pipe-guided hydraulic circuit of a Hydraulically Interconnected Suspension (HIS) often lead to vibrations of the whole pipeline and associated structures and hence become a source of structural noise. This paper presents an investigation of fluid induced vibration into the pipeline. The one-dimensional wave theory is employed to formulate the equations of motions that govern the dynamics of the fluid-structural system. Axial and one plane of lateral vibrations as well as the effects of shear deformation on the lateral vibration of the pipe are considered. The transfer matrix method (TMM) is applied to determine the steady state response of the fluid-structural system, which consists of various pipe sections, hose sections, damper valves, accumulators, supports and joints that connect separate pipe branches. The overall system transfer matrix including fluid and pipe mechanics is obtained by combining with field transfer matrices representing the motion of single pipe sections and hose sections and various point transfer matrices that describe specified junction conditions. The developed model of the hydraulic system is examined through simulations and laboratory based rig tests. The simulation results show the hydraulic components have apparent impact on the dynamics of combined pipe structural and fluid system. The experiments performed on a hydraulic circuit and the measured steady state responses of the circuit are compared with those obtained from the simulations. It is found that the developed model of the hydraulic system including the coupling with boundaries has a reasonable accuracy in the frequency range of interest. Copyright © 2011 by ASME.
