铝型线填充率对径向传力的影响研究
Exploring Influence of Filling Rate of Formed Aluminum Wire on Radial Force

碳纤维复合芯导线由碳纤维复合芯棒和铝型线构成，型线铝股结构型式填充率高，与圆线铝股传力性能不同，目前针对碳纤维复合芯导线填充率对径向传力影响的相关研究空白。本文对卡线器夹嘴夹紧时导线的受力状态进行了有限元仿真模拟，利用ABAQUS软件建立不同填充率导线结构模型，仿真得到不同填充率下导线铝型线和芯棒的应力情况，仿真结果表明导线夹持受力状态下，铝型线填充率会对导线外部受力向芯棒传递造成一定影响，随着填充率减小，导线铝型线和芯棒压应力逐渐变大。研究结果可作为1 660 mm2碳纤维复合芯导线用卡线器夹嘴长度优化设计参考依据。
Aluminum conductor composite core is made of carbon fiber composite core and formed aluminum wire, and the filling rate of the structure type of formed aluminum wire is high. It has different radial force performances compared with round wire. There is not enough research on the influence of filling rate of formed aluminum wire on radial force at present. This paper carried out the finite element simulation of stress states of the conductor clamped by grip jaw and established the structural model of the conductor that has different filling rates with the ABAQUS software. The simulation produces the stress states of the formed aluminum wire and carbon fiber composite core with different filling rates. The simulation results show that when the conductor is clamped with grip jaw in the stress state, the filling rate influences the transfer of the external force of the conductor to the carbon fiber composite core. As the filling rate decreases, the compressive stress of the formed aluminum wire and carbon fiber composite core increases gradually. The research results can be used as a reference for the optimal design of the length of the clamp of grip jaw for 1 660 mm2 aluminum conductor composite core
