  • In the present work we simulated the process of a sub-caliber projectile moving in the bore of a DAVIS gun using the finite element method based on the LS-DYNA calculation program.By loading the pressure of the gases from the propellant burning on the pushing module, we calculated the stress of the test accessories moving in the bore and checked its strength.Further, we verified the safety of the test accessories of the sub-caliber projectile using the simulation and the experimental results.This analysis can serve as a reference for refining the sub-caliber launching technique of the DAVIS gun and other guns.
