| 摘 要： | 由于捻角因素的影响，钢芯铝绞线在实际应用中往往会产生耦合效应。其中，拉-扭耦合效应对股线防滑具有积极作用。对拉-扭耦合效应的作用原理进行理论分析，以JL／G1A-500-54／7型钢芯铝绞线作为计算实例，最终获得该效应与股层节径比的关系，并为股线防滑提出了一些建议。

| Abstract: | The ACSR will produce simultaneously some coupling effects in practical application because of the impact of spiral angle.The tension-torsion coupling effect has a positive effect for the slip-resistance of strand wire.This paper takes the theoretical analysis about the tension-torsion coupling effect and selecting JL/G1A- 500-54/7 as a computation example.The relationship between the tension-torsion coupling effect and pitch di- ameter ratio is obtained ultimately,and some suggestions about slip-resistance of strand wire axe also advanced. |
