摘　　要：针对在高温超导储能磁体设计中多物理场耦合分析问题,本文提出了一种面向有限元分析的解耦优化设计方法,并以一台150kJ/100kW高温超导磁储能磁体为例进行了有限元仿真验证。本文首先梳理了高温超导储能磁体的多场耦合关系,提出在材料物性关系和多场耦合关系中分别以温度和电磁场为主导因素;进而归纳得出,磁体易失超危险区分布及解耦分析中多物理场数据流向设计,是设计过程中的关键问题,并给出了分析策略;最后按照逻辑合理、工作量最省的原则提出了解耦综合优化主流程,及针对易失超危险区的优化建议。Aiming at the problem of multi - physics coupling analysis in design of HTS - SMES magnet, a deeoupling optimal design method for finite element analysis was proposed, and a 150kJ/100kW HTS - SMES was used as an analytical case. Firstly, the multi - physics coupling relation of HTS - SMES magnet was classified and analyzed, and the temperature and electromagnetic fields were considered to be the core elements for the analysis of material properties and HTS - SMES magnet multi - physics coupling. Then, it was concluded that distribution analysis of the easy to quench zone and design of multi - physics data flow were key problems in the optimal design of HTS - SMES magnet, furthermore, the analysis strategy was given in this paper. Finally, according to the principle of reasonable logic and minimum work load, the general optimization process of deeoupling was put forward, and the optimization suggestion was given for the easy to quench zone.
