摘要
法拉第屏蔽是EAST装置ICRF天线的一个重要部件。鉴于法拉第屏蔽的结构安全性,通过运用有限元方法和公式对法拉第屏蔽在等离子体破裂和等离子体垂直位移事件两种工况下进行电磁和结构分析,获得了法拉第屏蔽在这两种工况下所受的电磁力、应力分布和变形情况。分析结果满足设计要求,并为法拉第屏蔽的结构安全性评估提供理论依据。
Faraday shield is one of the important components of ICRF antenna for EAST.In view of the structural safety of the Faraday shield,the electromagnetic and structural analyses for the Faraday shield have been carried out by applying the finite element method and the formulas under the cases of plasma disruption and vertical displacement event（VDE）.Results of the electromagnetic forces,the stresses distribution as well as the deformation in the Faraday shield have been obtained under the two cases.They meet the design requirements and provide the theoretical basis for the structural safety evaluation of the Faraday shield.
