In order to solve the problem that the aluminum-alloy conductor with ultra-high-strength steel reinforced is more easily broken in the fatigue test， the main parameters affecting the vibration strength of the conductor are studied. The equivalent bending stiffness of conductor is proposed， and the expression of dynamic bending strain of the conductor at the last point contact with the clamp is obtained. Aeolian vibration simulation tests are carried out by using indoor simulation test equipment with two different spans of 55 m and 140 m. The theoretical calculation is in good agreement with the experimental results， which verifies the availability of the model. The model of the conductor clamp outlet under the condition of breezy vibration and the analysis of the main influencing parameters provide a theoretical basis for engineering applications.
