| Abstract | Transmission lines are extremely flexible structures, which can suffer from galloping under extreme environmental conditions. A better understanding of the phenomena is therefore necessary to predict occurrence and extent of this phenomenon. In this study, an aero-elastic experiment has been performed on sectional model of four-conductor transmission line considering different structural configurations. The experiment is reproduced numerically using a nonlinear FEM code, in which aerodynamic force is estimated using quasi-steady and unsteady force model. Dependence of galloping on structural configuration and efficiency of aerodynamic force prediction models is investigated in light of experiment and simulation results. |
