Dynamic Analysis of the XM650E4 8-Inch Projectile

Abstract

A linear dynamic analysis of the XM650E4 8-inch projectile is obtained under a gun-launched environment. The chamber pressure, generating projectile motion, is examined for frequency content by a Fourier transform method. The response characteristics of the projectile are determined from a solution to the general eigenvalue problem. The finite element computer code, NONSAP, is utilized to solve the incremental equations of dynamic equilibrium by a direct integration method. A time-dependent representation of the solution is generated during projectile motion and demonstrates characteristics similar to results of available experimental data. The analysis also determined the response of the projectile to loading conditions approximating the sudden release of forces at muzzle exit.
