Wave Packet as a Model of Localised Disturbances Propagating along the Cables

Abstract:

In the paper localised disturbances propagating along the cables are modelled by wave packets. The motion of the cable was described in relation to its equilibrium state. The linear equations were used. Typically disturbances associated with sudden gust of wind are modelled by kinematic generator exciting oscillations in the specified frequency range, concentrated around the central frequency. The packet of binormal waves and coupled packets of normal and tangent waves were considered. The description of the evolution of the wave packets during their motion was presented analytically and numerically in the form of plots.
