Abstract

The automotive air conditioning hose is used for connecting the components of air conditioner in a vehicle. The hose is usually manufactured by the swaging process to connect the rubber hose with the metal fitting at the end of the hose. The swaging process leads to various stress and strain configurations in the hose, which give a critical effect on the hose performance. In this paper, the deformation characteristics of an air-conditioning hose during the swaging process were analyzed using the nonlinear finite element method. Especially the rubber layers, which are contacted with the metal fittings, were divided with finer mesh density than the reinforcement braids to increase the solution accuracy. The material properties were obtained from experimental data, and the contact conditions were used in consideration of the real manufacturing process.
