摘要
硬目标侵彻弹能够有效毁伤敌方地下工事等多层结构目标,为使弹丸能够在预定的层数起爆,利用侵彻加速度来实现计层。通过有限元仿真软件对弹丸正侵彻和斜侵彻多层间隔靶板进行仿真,获取弹丸碰击、侵彻和穿透靶板时的加速度特征,针对可能存在竖直墙的情况,引起多计层,提出分析水平和垂直加速度特征峰值以及设定侵彻间隔时间的办法,剔除其带来的影响,实现精确计层。通过Matlab对该方法进行验证,证明能确保计层策略的准确性。
Hard target penetration projectile can effectively damage the enemy’s underground works and other multi-layer structural targets.In order to enable the projectile to detonate in a predetermined number of layers,the penetration acceleration is used to achieve the meter layer.The finite element simulation software is used to simulate the forward and oblique penetration of projectiles into the multi-layer spaced target plate.The acceleration characteristics of projectiles impacting and penetrating the target plate are obtained.In view of the possible existence of vertical walls,which may cause multiple layers,the method of analyzing the peak value of horizontal and vertical acceleration characteristics and setting the penetration interval time is proposed to eliminate the impact of the projectiles and achieve accurate measurement of layers.The method is validated by Matlab,which can ensure the accuracy of the stratum initiation strategy.
