线性聚能装药对自锻弹丸干扰的数值模拟
Numerical Simulation of Interference Self Forging Projectile from Linear Shaped Charge
摘要
Abstract
To study the effect of linear shaped charge on the interference of self forging projectile at different angles,the whole process of interference self forging projectile from linear shaped charge at different angles (0°、30°、60°and 90°) and penetrating into No.45 steel plate after the self forging projectile was intercepted was numerically simulated by finite element software ANSYS/ls-dyna.The three stages of physical change in the process of penetrating the No.45 steel plate of self forging projectile with the jet head of shaped charge before meeting,meeting process and after meeting were analyzed through the Lsprepost postprocessing software.The optimum interferencing angle of interferencing the self forging projectile from linear shaped charge was determined through the comparative analysis of deflection distance,broken degree,penetration ability etc.after the self forging projectile is interference.The results show that the linear shaped charge can effectively interfere with self forging projectile,and the interference angle has a great influence on the effect of interference.In the range of 0° to 90°,the effect of interference is best when the interference angle is 60°.关键词
