ITER超导电流传输线导体等效模量的预测

Prediction of equivalent modulus of superconducting busbar for ITER

ITER超导磁体系统的超导电流传输线导体是由NbTi/Cu管内电缆超导体、辅助绝缘层和接地金属屏蔽层组成的层状复合材料结构。分别采用基于传统的复合材料理论和基于均匀化理论与复合材料损伤理论相结合的方法对超导传输线导体的等效模量进行了理论预测。这些结果为分析和计算超导电流传输线的应力和变形以及热性能提供了必要的参数。

The superconducting busbar of the 1TER superconducting magnets is of composite structure consisted of NbTi cable-in-conduit conductor, insulation layers and grounding metal net. The equivalent modulus of the superconducting busbar have been calculated based on the conventional composite theory and the method combining the homogenization theory with the composite damage theory, respectively. These results are necessary for analyzing and calculating the stress ,deformation and the thermal behavior of the superconductor busbar.
