摘要

HT-7U托卡马克低温恒温器是一个围绕整个基本机的大型真空容器，其外壳为圆柱形，顶部为碟形，底部为平底。HT-7U低温恒温器的主要功能是在环境温度测试大厅和液氦冷却超导磁体之间提供热障。施加在低温恒温器上的载荷有真空压力、自重、地震事件和涡流产生的电磁力。它还通过穿透为低温恒温器内外的所有连接元件提供进给。低温恒温器主要选用304L不锈钢。采用有限元程序对低温恒温容器在等离子体工作条件下的结构进行了包括屈曲在内的分析。应力分析结果表明，最大应力强度低于允许值。本文重点介绍HT-7U低温恒温器的结构分析。文中还介绍了低温恒温器的初步设计。

Structural analyses and preliminary design of HT-7U cryostat

The cryostat of HT-7U Tokamak is a large vacuum vessel surrounding the entire Basic Machine with cylindrical shell, dished top and flat bottom. The main function of HT-7U cryostat provides the thermal barrier between the ambient temperature testing hall and the liquid helium cooled superconducting magnet. The loads applied to the cryostat are vacuum pressure, dead weight, seismic events and electromagnetic forces originated by eddy currents. It also provides feed through penetrations for all the connecting elements inside and outside the cryostat. The main material selected for the cryostat is stainless steel 304L. The structural analyses including buckling for the cryostat vessel under the plasma operation condition have been carried out using a finite element code. Stress analysis results show that the maximum stress intensity was below the allowable value. In this paper, we emphasize on the structural analyses of HT-7U cryostat. The preliminary design of the cryostat is also described.

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
