| Popis: | To ensure its operational security, it is important to study the vibration state of transmission line. The equivalent viscous damping of aero-vibration for a large-span overhead conductor is obligated to be determined. In this paper, the damping characteristics of conductor by AACSR-400 steel core aluminum alloy wire are studied by use of energy balance principle. Based on the Diana wind energy curve and equivalent viscous damping, the relationship between frequency and damping ratio is conducted and discussed. Furthermore, a numerical simulation by ANSYS is performed to verify the validity of the equivalent damping coefficient and equivalent damping ratio with the same material parameters. Study shows that the result of finite element method by ANSYS is consistent well with that by energy balance principle. |
