Hysteresis Phenomenon in the Galloping of the D-Shape Iced Conductor [PDF]
Mathematical Problems in Engineering, 2013 It is well known that there is a hysteresis phenomenon in the amplitude variation in the iced conductor galloping with the wind velocity, which will have more obvious disadvantages to the overhead transmission lines. But hysteresis characteristics in the conductor galloping have not received much attention.
