摘要: 在以往的碳纤维复合材料芯导线(下文简称“碳纤维导线”)架设工程建设阶段的X射线检测工作中,除碳纤维复合材料芯棒(下文简称“芯棒”)常规的显性缺陷外还发现了一种其与楔形夹座不同心的现象,而此类缺陷未经过研究,长远影响尚未可知。本文基于碳纤维芯导线压接X射线的检测图像,对压接不同心现象进行了分析,给出了芯棒压接不同心的定义,并提出了造成芯棒压接后不同心的原因;根据导线、金具、芯棒参数,提炼出芯棒压接不同心的数值仿真模型,并建立起芯棒压接不同心所产生弯曲变形效应的有限元计算模型;然后,通过对芯棒压接不同心的弯曲变形力学问题的静力学仿真计算,分析了其在压接不同心环境中的静力学响应,评估了压接不同心造成的安全隐患,为碳纤维导线压接工艺的改善提供理论支撑。

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.
