This paper focus on the optimum design of arc-shaped rubber hose, so that hose has a good balance performance and higher burst pressure. Based thin shell theory without considering bending moments shear force, equilibrium equation was established to obtain internal force under pressure, pressure obtained by using Tsai-Hill failure criterion. According mechanical model influence structural parameters distribution vulnerable positions studied. Then, in order determine satisfying performance,...

The mechanical model related to the balance and stiffness characteristics of bellows type rubber hose under internal pressure was studied. Based on thin shell theory without considering bending moments shear force, equilibrium equation established obtain angle different environments. Considering deformation rope structure hose, divided into two stages, including winding deflection tensile fiber. Then constitutive anisotropic material introduced, physical characteristics. According model,...

This article focuses on the establishment of theoretical model for formation balanced curved rubber hose under pressure. According to rotation angle cord along axial direction in is same as that straight before forming, length was established. Then based thin shell theory without considering bending moments and shear force, deformation characteristics rope structure mechanical equilibrium hose, balance performance model, influence structural parameters studied. Eventually, finite element...

Abstract Filament-wound flexible pipes are widely used to transport fluid in pipeline systems, proved extremely useful marine engineering. The hyperbolic have good vibration suppression performance, but they easily deformed under internal pressure. This paper focuses on the stability of based composite Reissner shell theory and transfer-matrix method. nonlinear stretch reinforced filament fiber bridge effect considered model. calculation results show that a large winding angle reduces...

Abstract Fiber reinforced rubber pipes are widely used to transport fluid at locations requiring flexible connections in pipeline systems. The spherical self-balancing fiber with low stiffness drawing attention because of their vibration suppression performance under high internal pressure. In this paper, a theoretical model is proposed calculate the axial and lateral pipes. inhomogeneous anisotropy layer nonlinear stress-strain relationship considered model. accuracy verified by...

Abstract In this paper, the free vibration of rubber matrix cord-reinforced combined shells revolution under hydrostatic pressure is investigated by precise transfer method. Under pressure, deformation and stress are generated in composite shell. Based on characteristics rope structure, shell analyzed. The included differential equation motion form pre-stress. Then considering fluid-solid coupling boundary condition, field fluid-filled spherical obtained. By continuous condition state vector...
