本文分析了由一层圆形线螺旋缠绕在一层圆形直芯线上的简单线股。未变形的结构是一种特殊情况，在这种情况下，每一根周围的螺旋线都接触到它的两个相邻的螺旋线，也接触到芯线。这就形成了静不定接触问题。建立了一个简单的有限元模型来分析这种情况。数值结果表明，当钢绞线两端固定不旋转时，接触可以在所有可能的接触点同时发生。(c) 2007年Elsevier Masson SAS。版权所有。
This paper is concerned with the analysis of simple wire strands made from one layer of circular wires helically wrapped around a circular straight core wire. The undeformed configuration is the special case in which each of the surrounding helical wires touches its two adjacent neighbouring helical wires as well as touching the core wire. This forms a statically indeterminate contact problem. A simple finite element model is developed to analyse this situation. Numerical results show that contacts can occur simultaneously at all possible contact points when the strand is subjected to extension with both ends fixed against rotation.
