Abstract: On the base of the analysis for the stress of rubber hose
elbow subjected to inner pressure and the spiraled geometry of its
framework cords, the general formulation of neutral angle of its
framework cords is derived, and the control equation of spiraled angle
of the framework cords is yielded. The theoretical analysis and
experimental results indicate that when the spiraled angle of its
framework cords in rubber hose elbow is approach to neutral angle, the
deformation of hose as a result of inner pressure is small, that is, its
equilibrium performance is good.
Key words: Rubber hose elbow Equilibrium performance Neutral
