Aerodynamic Force Characteristics and stabilities of Two Typical Iced Conductors

Abstract:

This paper investigates mean and RMS (root mean square) aerodynamic force coefficients of quasi-oval and sector shape iced conductors by tests on their rigid section models using high frequency balance technique in wind tunnel. Then possibility of SDOF (single-degree-of-freedom) galloping is discussed based on the aerodynamic force coefficients. The results presented in this paper could be used as reference of similar analysis for general iced conductors and provide useful data for estimation of their wind induced response.
