Numerical analysis of the dynamic response of a 5-conductor expanded bundle subjected to turbulent wind
The paper describes a numerical model, i.e. a design tool, to determine the dynamic response of bundle conductors to turbulent wind excitation. The structure is modeled by means of finite element method and the force field exerted on each cable, as function of cable's relative position and velocity, which was derived by experimental measurement at Politecnico di Milano Wind Tunnel. The proposed methodology has been applied to a real case to define the spacers number and position along the span to avoid large conductors displacements.

Abstract

The paper describes a numerical model, i.e. a design tool, to determine the dynamic response of bundle conductors to turbulent wind excitation. The structure is modeled by means of finite element method and the force field exerted on each cable, as function of cable's relative position and velocity, which was derived by experimental measurement at Politecnico di Milano Wind Tunnel. The proposed methodology has been applied to a real case to define the spacers number and position along the span to avoid large conductors displacements.
