Swaging 시 P/S 호스의 변형 특성에 대한 유한요소해석

Finite Element Analysis for the Deformation Characteristics of a P/S Hose in the Swaging Process

It is necessary to analyze the mechanical behaviors of the power steering hose, which must play a proper role under severe operating conditions, in order to prepare a preventive measure fur contrary effects expected in unfavorable circumstances. In this paper, the stress and deformation characteristics of the hose components such as rubber, sleeve, nipple and reinforced braids during the swaging process, are analyzed using the finite element method. Contact conditions identical to the manufacturing process are taken into account, and the material properties based on experimental data are used in the analysis. Investigations into the mutual relations between the manufacturing conditions and the hose performances are done with respect to the jaw stroke on the basis of the stress and strain values of the hose components after swaging process.
