Simulation Analysis on Shielding Effectiveness of Rocket Projectile

In order to analyze the shielding effectiveness of the rocket projectile in the electromagnetic environment, the electromagnetic simulation model of the rocket motor was established by using the ANSYS HFSS electromagnetic simulation software, the shielding effectiveness of the rocket projectile motor was calculated, and the influence of the structural charactetristic parameters of the rocket projectile motor on the shielding effectiveness was analyzed, the distribution law of shielding effectiveness with frequency parameters and position parameters were obtained, which provided support for evaluating the electromagnetic environment safety of rockets projectile.
