Analysis Impact of Tube Coning for Initial Projectile Disturbance
摘要
Abstract
According to the theory of strength,there is a screwshaft cone when designing artillery tube.The coning of the screwshaft cone can influence the stiffness of tube near muzzle. Stiffness pellet size for the initial disturbance influence of worthy research.Concerning this issue,the projectile-barrel coupling dynamics finite element model of some large caliber artillery is established and then the movement rule of projectile in the bore is calculated when the coning is 0o、0.38o、0.73o、and 1.17oin different working conditions.The analysis shows that under the precondition of keeping tube quality and centroid invariant,for some large caliber artillery,the smaller the tube coning namely the thicker and the higher the stiffness of the tube near muzzle,the more benefits decreasing initial disturbance of projectile.关键词
