Abstract
According to the actual structure of steel wire wound reinforced rubber flexible pipe, using the finite element software ANSYS, 3-D finite element model of flexible pipe is established. For the mechanical response of flexible pipe under internal pressure, the comparison on the result by numerical calculation, the static loading test and the result by analytic method shows that the 3-D finite element model of flexible pipe is rational. Moreover, based on the finite element model of flexible pipe, the influence of internal pressure, spanning length and reinforced steel wire diameter on the axial stress of the innerest steel layer and the Mises stress of the innerest rubber layer is analyzed.
