Abstract
Orbital electromagnetic launch is the most widely used type of electromagnetic launch method. The strong electromagnetic radiation and electromagnetic interference in the launch process will not only damage the electronic components inside the smart munition, but also produce magnetic leakage near the munition, which threatens the safety and stability of the weapon system. Therefore, this paper proposes two electromagnetic shielding body structures, and through finite element simulation analysis, comparing the magnetic field distribution before and after adding the shielding device, it can be seen that after setting the shielding body, the magnetic induction intensity inside the launch barrel decreases, and the magnetic induction intensity inside the double shielding layer is almost zero. This indicates that the provision of shielding body can play a role in weakening the magnetic field, which can effectively solve the influence of strong magnetism on the missile during the electromagnetic launch of the rail.
