摘　　要：针对碳纤维复合芯导线高温低弧垂的特点,采用ANSYS有限元分析软件分析碳纤维复合芯导线在0~160℃的弧垂变化规律,并验证了有限元软件模型和加载方法的合理性。通过分析碳纤维复合芯导线在温度荷载作用下的弛度特性,表明芯棒截面积相同时结构重量小的导线弧垂变化量大;芯棒截面积不同时,截面较大的导线弧垂变化量较小。According to the characteristics of aluminum conductor composite core on high temperature-low sag, the finite element analysis software ANSYS is used to analyze the sag change regular pattern of aluminum conductor compos- ite core at 0~160 ＊C. And then the rationality of finite element software model and the loading method are verified. By analyzing the sag characteristics of aluminum conductor composite core at the temperature loads, it shows that more weight wire has small changes in volume conductor sag when the wire has the same cross-sectional mandrel area; different cross-sectional area of the wire, the sag variation of larger cross-sectional wire is small.
