摘要:

用ANSYS有限元软件计算了等离子体破裂时真空室上的涡流、电磁力和应力。有限元模型包含了基本的第一壁部件,以更加准确地研究真空室在瞬态电磁力作用下的结构强度。结果表明,高场侧靶板和内靶板带给真空室较大瞬时应力,但真空室的结构强度仍然满足强度要求。分析可校核和改进第一壁部件的结构设计。

Abstract:

The eddy current, electromagnetic force and stress are computed using the ANSYS finite element software for the vacuum vessel during the major plasma disruption. The model contains the basic plasma facing components to learn the structure strength of the vacuum vessel under the transient electromagnetic force more accurately. The results indicate that high transient stress on vacuum vessel is brought by the high field plate and the inner plate, but the vacuum vessel is still strong enough to bear the electromagnetic loads. This analysis can help to check and improve the design of plasma facing components.

Key words: EAST, Vacuum vessel, Plasma facing components, Plasma disruption, Eddy current, Electro- magnetic force, Stress
