摘要

针对位于国际热核聚变试验堆(ITER)装置上端口的直流辉光放电清洗(GDC)电极的概念设计模型,该文利用ANSYS APDL语言对GDC电极在等离子体破裂过程中所受的电磁力进行了计算分析。在ITER有限元整体模型的基础上,将电极嵌入整体模型,采用在相应接触面上建立约束方程的方法,使局部和整体模型相耦合,实现了ITER装置在等离子体破裂事件下的三维暂态电磁场有限元计算,得到了GDC电极中的感应电流分布及其所受的电磁力,计算结果为ITER GDC电极概念设计提供了参考。

Abstract：

Safety performance assessments are very important for the ITER (International Thermonuclear Experimental Reactor) GDC (glow discharge conditioning) conceptual design. This paper introduces a force analysis of the ITER GDC electrode using ANSYS APDL. The electrode model is imported into the original ITER finite element model. The partial and global models are coupled by the model processing and constraint equations are generated for the contact surfaces. The method is then used for three-dimensional transient electromagnetic field computations with plasma disruption. The predicted electromagnetic force on the electrode support for the ITER GDC structural analysis.

Key words： International Thermonuclear Experimental Reactor (ITER) transient electromagnetic field electromagnetic force
