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 experimental results. Theoretical calculation finds that both influenced significantly key structural parameters pipe (the length, circumferential radius end, meridional radius, initial winding angle). can be reduced remarkably optimal angle, without any side effect on self-balance pipe. investigation methods results presented paper will provide guidance for design future.
