英文摘要 | The Comprehensive Research Facility for Fusion Technology (CRAFT) is a large scientific device in China's 13th Five-Year Plan. The RAMI (reliability, availability, maintainability, and inspectability) analysis method is used to control the technical risk of the CRAFT cryogenic system, which can better guarantee the stable operation of the CRAFT system. Functional breakdown is performed first to understand the functions of the CRAFT cryogenic system, and then IDEFo diagram is used to describe the hierarchical structure and relationship between each function in the cryogenic system.& nbsp;A preliminary RAMI analysis of 200W@4.5 K helium refrigerator system with the main function of DF1 was carried out. Failure mode, effect and criticality analysis was used to identify and evaluate the failure mode of 200 W helium refrigerator. A criticality chart of the failure mode was drawn based on the evaluation results. For the failure modes with medium and high risks in the initial criticality chart, there was no high risk after risk mitigation measures were taken.The logical basis of the reliability block diagram was obtained from the structural relationship between each function described in the IDEF0 diagram. Based on these logical structures, a reliability block diagram composed of components that implement basic functions was drawn. Input reliability data to calculate the reliability and inherent availability of the main function DF1.The results of Reliability block diagram analysis showed that the inherent availability can be greatly improved after taking improvement measures such as preparing spare parts to reduce the mean time to repair. Reliability was also greatly improved when measures such as regular inspection and maintenance were taken to reduce the failure rate. |
