三芯海底电缆中光纤与缆体应变关系的有限元分析方法
The analysis of finite element method on the strain relationship between optical fiber and cable in three-core submarine cable
摘要
Abstract
In order to make use of the distributed optical fiber strain sensing technology to measure the strain of the three-core fiber composite submarine cable , the finite element method is used for modeling , solving and analyzing .The conductor screen, insulation screen, semiconductor resist layer and filling layer are merged to insulation layer .The model is simpli-fied and ignores the brass band , armored cushion and coating .The model is used to analyze the dynamics of the model by using the SOLID164 element.The uniform load is applied to the tensile simulation test .The strain of the copper conductor , XLPE, lead alloy, steel armor and optical unit is fitted by using the least square method , and their functions are obtained. The results of the model can meet the characteristics of elastic and plastic materials .It provides reference for the research of mechanical properties and judgment the operation conditions of submarine power cable .关键词
