装药参数对整体式多爆炸成型弹丸成型的影响
Effect of Charge Parameters on Formation of Integral Multiple Explosively Formed Projectiles
摘要
Abstract
To improve the damage ability of integral multiple explosively formed projectiles (MEFP),the effect of configuration parameters of charge on projectile formation was studied using LS-DYNA code.Results show that the charge spacing has great effect on the shape and the radial dispersion angle of surrounding projectile.With increasing the charge spacing,the velocity of integral MEFP and the length-diameter ratio of central projectile change in small ranges,but the shape of surrounding projectile changes from rods to ball shape gradually.The trail of surrounding projectile decreases gradually and the flight stability of projectile enhances.With increasing the charge spacing,the radial dispersion angle of surrounding projectile decrease gradually.With increasing the length-diameter ratio of charge,the velocity and length-diameter ratio of central projectile increase significantly and the penetration performance enhances.The shape of surrounding projectile changes from ball to rods shape gradually.The trail of surrounding projectile increases gradually and the flight stability of projectile decreases.With increasing the length-diameter ratio of charge,the radial dispersion angle of surrounding projectile increases firstly and then decreases,so selecting a suitable lengthdiameter ratio of charge could improve the damage effect based on definite aim.关键词
