摘　　要：针对钻地弹对厚度不明目标的起爆控制存在加速度卸载后弹丸还未完全穿出靶标,侵彻引信难以准确实现起爆控制的问题,提出基于混凝土侵彻响应特性的空穴起爆控制方法。该方法利用理论分析和数值计算给出弹丸侵彻过程,并计算得到某弹丸以不同速度侵彻不同厚度靶板的侵彻过程数据,以此为依据,提出根据弹丸初速和侵靶时间进行出靶后自适应延时的空穴起爆控制的方法。经过算法验证,结果表明该方法能够有效地实现弹丸侵彻不明厚度的单层目标时的引信精确起爆控制。In order to achieve the accuracy control of earth penetrating weapon at high speed penetrating into unknow hard target,a void identification method based on concrete-penetration response characteristic was presented.By this method,the resistance characteristics of concrete to penetration projectile were obtained,a calculation method was established based on the mechanical analysis,and the void Identification design principle was presented.The method is tested by a measured data,and the void identification method was correct.
