Zusammenfassung

This paper deals with the dynamic analyses carried out to determine the aeolian vibration behavior of the All Dielectric Self Supporting Optical Cables (ADSS). The vibration numerical simulation usually requires two main tests giving the cable self-damping and the flexural stiffness EJ. Considering the long lasting experience gained on metallic cables, both the power method (PM) and the inverse standing wave ratio (ISWR) have been considered, in order to evaluate the cable self-damping. Some improvements, proven to be necessary in transferring the methods to the ADSS cables, are then described. Results from a standardized fatigue test are also shown and critically discussed.
