摘要

基于Abaqus/Explicit准静态分析方法,对电缆聚氯乙烯绝缘层的热变形过程进行了有限元分析,并将模拟结果与实验结果进行了对比。结果表明,计算得到的压痕深度等结果与实验测试数据较为一致,验证了计算模型的准确性。同时,分析了不同绝缘层结构尺寸对材料热变形的影响,获得了绝缘层压痕百分数与其结构尺寸的函数关系,讨论了给定压痕百分数条件下,绝缘层的结构尺寸与导体截面积的关系。为电线电缆产品热变形响应预测及绝缘厚度设计提供参考。

Abstract

Finite element analyses on thermal deformation process of polyvinyl chloride insulation of cable were carried out by using quasi-static analysis based on ABAQUS/Explicit. The finite element results were verified by the experimental results,indicating an adequate solution of thermal deformation behavior. Meanwhile,thermal deformation behaviors for various structural parameters were studied. The fitting functions of the indentation percentage and structural parameters of insulation were obtained,as well as that of the structural parameters and cross-sectional areas for a given indentation percentage level.The work can provide some references for characteristic prediction and insulation thickness design of wire and cable products.
