| Abstract |
A mathematical model of the dynamics of deformation of an overhead power line wire in a spatial setting is developed, the equations are solved on the basis of the finite difference method in an explicit scheme. In some cases, the accuracy of the calculations is compared with the obtained analytical solutions. A numerical study of the loading of a power line under the combined influence of wind and weight load was carried out. A numerical method for calculating wire breakage and the movement of parts after a break is proposed. The mechanism of the appearance of oscillatory motion such as "dancing wires" under the action of a variable wind load. The process of thermal conductivity and the dynamics of line deformation during melting of icing on wires by heating is studied, the transient processes of deformation of the power line are studied. |
