Study on the Influence of Pitch Diameter Ratio on Contact Mechanics Parameters between the ACSR Strand

Abstract:

Fretting damage generates under the breeze vibration condition. Fretting wear under various pitch diameter ratio at the ACSR strand interface has been studied by FEM method with the LGJ-25/4 ACSR taken as an example. The contact mechanics parameter distribution laws at the strand interface have been obtained. It shows that the peak of von Mises stress, contact pressure, contact state and shear stress at the contact spot decrease as the pitch diameter ratio increases. And the width of yield area also decreases as the pitch diameter ratio increases.
