The dynamical models for vibration research of electricity transmission line wires and air communication cables in a windstream

摘要

The dynamical models designated for vibration research of electricity transmission line wires arcommunication calles in the sfran between piers under periodic loading aresing in a wind stream by whirl frustration (Carman's whirl track).One of the variants of the method of initial parameters and dynamic rigidities in matrix form is bases itself on construction of dynamical models of the researched system "cable-protector-vibration damping". The developed dynamical model embracespractically any constructive realizations.Some examples of calculation are given to show a choice of constructive parameters of protector and the place of installation of stockbridge's extinguishers providing the best vibration damping.
