Simulation Studies on Launching Intensity of Certain Projectile

Dynamic simulation model of a certain high speed projectile in launching process was established based on non-linear transient dynamics theories, tested material parameters and bore press curve. Launching intensity of this model was simulated and analyzed using numerical simulation methods. Simulated results of intensity parameters at different times were obtained, which matched with experimental results very well. The content and method could be offered for theory reference and basis for the improvement of this high speed projectile and launching intensity research work of similar projectiles in the future.
