摘      要：Most finite element models of small arms focus on an idealized barrel,typically one with a perfectly straight bore *** five different experimentally measured bore centerlines,this investigation analyzes the effect centerline nonlinearity has on projectile exit *** includes the effect of rotating a centerline through several *** using Abaqus/Explicit,this dynamic analysis simulates a single firing cycle for each *** jump is calculated for each model as a measure of the effects of warped *** warped centerlines have a small effect on barrel dynamics.
