Mechanical Behaviors of a Power Steering Hose Assembly during the Swaging Process
In this study, finite element analyses for the mechanical behaviors of a power steering hose assembly during the swaging process were performed in order to investigate the stress level of hose components according to jaw strokes, and to examine the effect of friction coefficient on the contact force. The physical properties such as Mooney-Rivlin constants of rubber materials and the work-hardening data of the steel were obtained through the experiments, and the contact conditions identical to the swaging process were taken into account. Two reinforced layers included in the hose were modeled with axisymmetric rebar elements in the general-purpose program, MSC MARC2000. The updated Lagrange formulation and the large displacement option were employed in the analysis. The result interpretations were focused on the rubber components which are in contact with the metal components, because of their important roles in the hose efficiency.
