Finite Element Analysis of Hydraulic Hose Couplings 860818

This paper presents a finite element methodology and algorithm for predicting the deformation and stress response of high pressure hose couplings and components during the fabrication process and during service loading conditions. The method is demonstrated for a hydraulic cord-reinforced rubber hose coupling. Results are presented for predicted rubber stresses, contact pressures between the rubber hose and metal insert, contact geometry profiles, and the crimping force-deformation response during crimping. The methods presented here should be useful for design of improved hose couplings.
