ITER诊断插件电磁分析及其对结构的影响

Electromagnetic analysis of diagnostic port plug and its influence to structure of ITER

应用ANSYS软件建立模型并模拟了ITER诊断插件所处的物理环境,进行了电磁分析,获得了涡流和电磁载荷变化趋势。将电磁载荷耦合到结构模型获得了其对结构的影响。通过计算,获得了结构的应变和应力分布,这可作为评估诊断插件结构可靠性的依据。

In order to study the influence on the diagnostic plug caused by plasma disruption of ITER,ANSYS was used to build the model and simulate its physical environment for electromagnetic field analysis and obtain the trend of eddy current and electromagnetic load.The electromagnetic loads were coupled with the structure model to obtain its influence on the structure.The strain and stress distribution of the structure were obtained,which offer the basis for evaluating the diagnosis plug structure reliability.
