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