摘要

这一贡献的重点是利用螺旋线股的详细有限元模型研究电缆弯曲变形过程中发生的非弹性结构效应。由于电缆结构复杂,通常由同轴缠绕的导线、屏蔽层和外护套组成,因此必然存在非弹性变形行为。在这项工作中,我们将简化的电缆建模为用二次梁单元离散的螺旋钢丝股,以研究几何参数的影响,如钢丝的螺旋角和钢丝的相互作用,通过无摩擦或摩擦接触模型。从较低的模型复杂度开始,我们使用双线和七线模型来模拟缠绕线的纯弯曲,忽略了材料的非弹性,以避免结构和材料效应的叠加。考虑到在未变形的七线股结构中接触状态的不同变化,允许直接观察主动接触对股弯曲响应的影响。对电线和电缆束组件中相关对象之间的相互作用建模的第一步,例如电缆领带或夹子,为双线模型提出。所提出的模型为研究影响索变形行为的具体结构参数提供了一个有价值的工具箱。

Effective Inelastic Bending Behavior of Multi-Wire Cables Using Finite Elements Accounting forWire Contact
This contribution focuses on the investigation of inelastic structural effects occurring during the bending deformation of cables using detailed finite element models of helix wire strands. Due to the complex structure of cables usually consisting of con-centric layers of intertwined wires, shields and the outer jacket, inelastic deformation behaviour has to be expected. In this work, we model simplified cables as strands of helix wires discretised with quadratic beam elements to investigate the influence of geometric parameters such as the helix angle of the wires and the interactions of the wires by means of frictionless or frictional contact models. Starting at low model complexity, we use double wire and seven wire models to simulate pure bending of intertwined strands omitting material inelasticity to avoid superposition of structural and material effects. Different variations of contact states in the undeformed configuration of the seven wire strand are taken into account allowing for the direct observation of the influence of active contacts on the strand’s bending response. First steps towards modelling the interactions between wires and objects relevant in cable bundle assembly, e.g. cable ties or clips, are presented for the double wire model. The presented models yield a valuable toolbox for the investigation of specific structural parameters affecting the deformation behaviour of cables.
