Abstract In this paper,two kinds of quad-bundled iced-conductors of crescent-shape are tested and simulated in order to analyze their stabilities. The approximation curves of aerodynamic force coefficients are obtained by applying polynomial curve fitting on the results of fluid/structure coupled finite element method. Then stability of SDOF(single-degree-of-freedom) galloping is discussed based on the two existing aeroelastic stability criteria. The results presented in this paper can provide useful data for estimation of the wind induced response of the quad-bundled iced-conductors.
