Abstract

Abstract: The forces of the bolts applied are analyzed by analytical calculation. All the bolt preloads are calculated and all the bolt parameters are designed. The loosening prevention of the bolt is introduced. Engineering test studies of full-scale for the bolts model and the assembling model of the gravity support(GS) structure are presented in order to improve the reliability of the bolts for the new designed GS, which offers the engineering reference for the bolt structure design of the ITER TF magnet GS.

Key words: ITER gravity support, Bolt preload, Analytical calculation, Full-scale test

摘要： 用解析法分析了螺栓的受力情况，计算出了螺栓的预紧力，设计了各种螺栓的参数，介绍了变更设计中用超级螺栓来防松的问题，提出了用全尺寸的螺栓模型和支撑结构的装配模型进行实际工程测试研究来增加设计的可靠性，为ITER纵场磁体支撑的螺栓结构设计提供了工程参考。
