摘　　要：背场线圈和杜瓦对CRAFT系统的运行具有重要影响。为了确保系统运行的稳定性,本文基于无力矩理论、线性振动理论和随机振动理论并采用有限元法,对杜瓦和背场线圈的静力学特性、模态响应和随机振动特性进行了研究,研究结果表明磁体系统在地震载荷的冲击下将会产生较大的变形。为此,以磁体及杜瓦的变形为优化目标,采用优化设计方法对磁体及杜瓦在不同载荷下的响应进行研究,从而获得最优设计方案。该研究工作将为后续超导磁体测试平台的加工制造以及抗震优化设计提供理论指导。The background field coil and cryostat have significant impact on the operation of CRAFT system.In order to en⁃sure the stability operation of the system,based on the theories of no-momentum,linear vibration and random vibration,the static characteristics,modal response and random vibration characteristics of cryostat and background field coil were studied by u⁃sing finite element method.The research results show that the magnet system will produce large deformation under the impact of earthquake.Therefore,taking the deformation of the background field coil and cryostat as the optimization goal,the optimal de⁃sign was carried out to study the response of the background field coil and cryostat under different loads,so as to obtain the opti⁃mal design scheme.This study in the paper will provide theoretical guidance for the fabrication and seismic optimization design of the superconducting test platform in the future.
