Abstract

Abstract: In the previous X-ray inspection work during the Aluminum Conductor Composite Core (hereinafter referred to as "ACCC") construction, despect of conventional obvious defects on the carbon fiber composite core (hereinafter referred to as "core"), it is also non-concentric with the wedge holder. Such defects have not been studied, and the long-term impact has not been known. Based on the X-ray inspection image of ACCC crimping, this paper analyzed the crimping non-concentric, defined the core crimping non-concentricity, and proposed the reasons for the core crimping non-concentricity. According to the construction parameters, this paper carried out a numerical simulation model, and the bending deformation effect finite element calculation is built. Then, through the static simulation calculation on the bending deformation mechanics problem of core crimping with non-concentricity, this paper analyzed the static response of the core, and evaluated the safety hazards caused by core crimping non-concentric. The research can provide theoretical support for the improvement of ACCC crimping.
