Abstract
In order to compare dynamic responses of gun barrels with uniform rifling,increasing rifling and combined rifling,the dynamic analysis method was used to analyze the changing rules of the driving edge force,the axial acceleration of the projectile constrained by rifling and muzzle vibration responses for different rifling style.The results show that,near the muzzle,the driving edge force is lowest for the uniform rifling but largest for the increasing rifling.The driving edge force curve for the uniform ri-fling is smooth,however,for the combined rifling the force changes severely and the curve has large gradient.As soon as the nose of the projectile exits the muzzle,the driving edge force for the combined rifling changes more than three times suddenly and the axial acceleration of the projectile constrained by combined rifling has a jump near the muzzle.Compared with uniform rifling,the muzzle rotation veloci-ty and rotation acceleration around the barrel axis increase about 92.7% and 367.5% respectively for the combined rifling.The uniform rifling is benefit for the projectile moving stably in bore and benefit for weakening the muzzle vibration.关键词
