摘要
考虑碳纤维复合芯导线的结构、材料特性,针对JRLX/T-315/40碳纤维导线进行了静力线形分析,并利用SOLIDWORKS软件建立导线实体模型,模拟分析了导线在实际运行过程中受到拉力、剪力和弯矩以及线夹的挤压力时外层股线与线夹接触部位的应力分布情况。结果表明,导线夹持区的应力集中部位主要在U型螺栓出口处和悬垂线夹出口处;在线夹出口处,T_0=0.15Tp时导线与悬垂线夹接触位置的外层中间一根股线的应力损伤最严重;在弯矩和拉力共同的作用下,碳纤维复合芯棒承担导线63%左右的应力,是碳纤维导线的主要承力部件。
Considering the structure and material properties of ACCC,static linear characteristics of the ACCC JRLX/T-315/40 was analyzed.SOLIDWORKS software was adopted to establish ACCC solid model.And then this paper analyzed the tension,shear force and bending moment of the conductor,and simulated the outer contact strands stress distribution during actual operation.The results show that the stress concentration area of the wire clamp mainly occurs at the outlet of the U-shaped bolt and suspension clamps.At the outlet of the clamp,the most serious damage stress positions appear in the suspension clamp and the ACCC with the contact position of the outer layer of strand at 15% of the calculated tensile force.Under the action of bending moment and tension together,the mandrel bears about 63% of tension,and it is mainly responsible for the tension.
