Abstract

Abstract

On the basis of analysis of the fluid drag acting on a suspended cable subjected to transverse fluid excitation,an expression is established for the fluid forces applied on the cable.By using a coordinate transform,the equations of motion of the cable are simplified into those in terms of the stretch and rotation coordinates.In the case of small ratio of sag-to-span,a study is made on the fluid-induced vibration behavior of the cable,including the critical fluid flow speed,the stability of equilibrium position,as well as the influences of gravitational parameter on the cable dynamics.
