柱面靶板的运动对动能弹侵彻能力的影响
Influence of the Movement of Cylindrical Target Plate on the Penetrating Ability of Kinetic Energy Projectile
摘要
Abstract
In order to study the influence of the movement of cylindrical target on the penetrating ability of kinetic energy projectile, the finite element model of the projectile and the cylindrical target with axial and circumferential motion velocity was established by Truegrid software.The finite element software LS-DYNA was used to simulate the penetration process, and the curve of the kinetic energy mass and velocity as a function of time was calculated.The results show that the kinetic energy projectile penetration ability is greatly affected by the target motion.Under the same initial velocity of the projectile, the static target can be successfully penetrated, and the mass loss rate of the projectile is only 30.1％;the moving target is not penetrated, and the mass loss rate of the projectile is as high as 87.2％, but the damage area to the target is greatly improved.The velocity variation curve of the projectile along the x, yand zaxes is fitted, and the influence of the target motion on it is analyzed.It provides a reference for further research on kinetic energy projectile penetrating high-speed targets.关键词
