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.
