摘　　要：强电磁冲击环境的核心执行机构是线圈,除保障强磁环境发生线圈的电磁特性外,还须确保线圈支架具有充足的机械特性。在完成对线圈磁电设计的基础上,根据线圈的三维结构图、材料配置、质量分布、各零部件之间连接方式以及线圈固定方式等,建立线圈支架结构整体系统有限元计算模型,对线圈支架系统进行静力、稳定性数值计算分析,并校核联接件强度,为线圈支架结构提供参考依据。对实用大型强磁冲击系统所用线圈整体的力学结构进行设计分析,应用背景较新,且仿真计算过程严格按照实际搭建尺寸进行,具有高度的一致性,为后续搭建强磁环境发生装置提供坚实基础。The core actuator in a strong electromagnetic shock environment is the coil. In addition to ensuring the electromagnetic characteristics of the coil in a strong magnetic environment, it is also necessary to ensure that the coil support has adequate mechanical characteristics. On the basis of the completed magneto-electric design of the coil, the finite element calculation model of the overall system of the coil support structure was established based on the three-dimensional structure drawing of the coil, the material configuration, the mass distribution, the connection method between the components and the coil fixation method, etc. The numerical calculation analysis of the static force and stability of the coil support system was carried out and the strength of the coupling was checked to provide a reference basis for the coil support structure. The design and analysis of the overall mechanical structure of the coil used in the practical large-scale strong magnetic shock system is relatively new, and the simulation calculation process is strictly in accordance with the actual size of the construction, with a high degree of consistency, providing a solid foundation for the subsequent construction of the strong magnetic environment generator.
