Abstract

Abstract According to elastic thin shell theory, balance and physics equations of Flexible Arc Pipes are set up in this article. The parametric correlation expression between axial deformation and axial force is deduced. Consequently, parameterized calculation method on equilibrium performance and static stiffness is presented. The influencing factors of equilibrium performance and static stiffness of the pipe are analyzed. As a result, when the structure geometry is decided, the pipe equilibrium performance and static stiffness lie on the product of elasticity module and thickness. The smaller of the product, the better of equilibrium performance and the larger of static stiffness. Otherwise, the worse of equilibrium performance and the smaller of static stiffness.
