The Strength Analysis of Pre-Tightening Force on Covering Pipe-Ear

Abstract:

The covering pipe-ear is one of the important components of the overhead contact line system (OCS) for supporting loads. The finite element model of covering pipe-ear was established, as the pre-tightening force, wind load and ice load all have effect on it, the stress distribution law were simulated under 12 kinds of loading conditions. The results show that the pre-tightening force has remarkable influence on covering pipe-ear and 2500N pre-tightening force is appropriate for the aluminum alloy covering pipe-ear. It is useful for the catenary components static strength reliability design.
