The aerodynamic coefficients of each subconductor in an iced quad bundle conductor covered with crescent-shaped and sector-shaped cross-sections were determined by the wind tunnel test. A cable element with torsional degree of freedom used to simulate the iced conductor is obtained in ABAQUS software by releasing the two bending degrees of freedom and setting the material to be incompressible. The...
The aerodynamic coefficients of iced quad-bundled conductor varying with attack angle determined by wind tunnel test are presented. A cable element with torsional degree-of-degree used to simulate the iced conductor is obtained in ABAQUS software by releasing the two bending degrees-of-freedom and setting the material to be incompressible. The aerodynamic loads varying with attack angle are applied...
The galloping of iced quad-bundled conductor under the action of stochastic wind load is investigated. A three-node cable element with three translational and one torsional degrees-of-freedom at each node is employed to discretize the bundled conductor and the two-node Euler-Bernoulli beam elements are used to simulate the spacers. With the Kaimal spectrum and the Davenport mutual spectrum, the samples...
