CONSIDERATIONS ABOUT GALLOPING PHENOMENON AND THE DETERMINATION OF MATHMATICAL RELATIONS abstract

The reduction of negative effects of the galloping phenomenon of aerial conductors would be achieved by the detailed know ledge of the phenomenon and its mathematically expresses. The mathematically expresses of the galloping phenomenon take account of participation factors to this phenomenon as: the variation of the speed of the wind, the Ice formation an the round conductors, the aerodynamic force and Its components, the lift coefficent the external force friction, the resisting stiffness of the cable, the torque, the inertia moment, the aerodynamic moment and the angle of attack. Related to this phenomenon, it establishes relations of the beggining of galloping phenomenon depending on critical speed of wind and all the participation factors to this phenomenon.
