摘要：
By applying high frequency balance technique on rigid section models in wind tunnel, aerodynamic force characteristics of cylinder, bare conductor and six quasi-oval shape iced conductor models were investigated in different turbulence intensities and wind directions. Galloping instability of quasi-oval shape iced conductor models were also studied. The analysis shows that absolute values of the force coefficients decrease with the increasing turbulence intensities and the shape of the iced conductors, wind directions have great influences on the force coefficients acting on the conductors and galloping of quasi-oval shape iced conductors can occur in some wind direction. The results could be used as the basis of analysis of their wind induced response and failure mechanism.
