FINITE ELEMENT ANALYSIS OF CONTACT CHARACTERISTIC OF OVERHEAD CONDUCTOR IN AEOLIAN VIBRATION

Overhead transmission line is mainly aluminum conductor steel reinforced( ACSR),which is prone to occur fatigue fracture and fretting wear because of the action of the long-time aeolian vibration. A finite element model of the contact between conductor strands was built to carry on the simulation on...

description Overhead transmission line is mainly aluminum conductor steel reinforced( ACSR),which is prone to occur fatigue fracture and fretting wear because of the action of the long-time aeolian vibration. A finite element model of the contact between conductor strands was built to carry on the simulation on the stress distribution of the conductor in different static pretension and the dynamic mechanics in aeolian vibration. The results show that the contact stress of strands increase with the pretension,and the stress increment is maximal when the pretension increases from 20% T to 25% T. The contact point stress distribution in axis of the strand is uniform while the pretension is less than 20% T and is uneven while the pretension is more than 20% T. In the condition of arolian vibration,the stress in constrained position and the middle of the test conductor which is imposed vibration is the maximum. Meanwhile,the contact points stress distribution of the same layer is uniform and the contact stress of adjacent layers in axis is cyclical. The frequency has less impact on the amplitude and the fretting displacement.
