Mechanical oscillations on overhead transmission lines

, 2014
D.Ing. (Mechanical Engineering) This research proposed to develop a mathematical model for the prediction of aeolian vibration levels on overhead transmission lines in order to be able to ensure that damping systems are designed optimally in future. In order to enhance the understanding of aeolian and wake-induced vibration further, it also proposed to
