摘要
The Aeolian vibration wear test of the self-damping conductors for large crossing was carried on a fretting fatigue wear test-bed. This test has been finished in three different vibration times under 25% ultimate tensile strength (UTS). The morphology observations and dimension measurement of aluminum wire wear scar has been analyzed by means of scanning electron microscope (SEM) and DMR multifunctional microscope. By observing the surface morphology and composition of the conductors, the influence law on the wire wear has been analyzed, and the analysis results reveal the contact wear mechanism, which is basically in accord with the working wires. The result shows the worn spots of the transmission line is an elliptic shape. The test result has important guiding meaning in further study on wear characteristics of self-damping conductors for large crossing under aeolian vibration.
