摘　　要：以灌封后的全电子安全系统(ESAD)为研究对象,运用显式动力学仿真软件得到了弹丸侵彻4层混凝土靶板的全电子安全系统动态过载响应特性,同时利用依据弹丸位置变化推断出的穿靶时间窗与穿靶速度变化,提出了一种基于数值积分的过载信号滤波通带算法。考虑到数字滤波器难以满足系统的实时性要求,设计了低通模拟滤波器,通过半仿真实验,结果表明,算法得到的截止频率对过载信号进行的滤波效果好,层信号明显。Taking the electronic safety and arming device(ESAD)after encapsulation as the research object,this paper obtains the dynamic overload response characteristics of ESAD in which a projectile penetrates four-layer concrete targets by using an explicit dynamics simulation software.At the same time,a passband algorithm of overload signal filtering based on numerical integration is proposed by using the time window and the velocity variation of the target penetration deduced according to the change of projectile position.Considering that it is difficult for the digital filter to meet the real-time requirements of the system,a low-pass analog filter is designed.Through the semi-simulation experiment,the results show that the cut-off frequency obtained by the algorithm has good filtering effect on overload signals,and the layer signals are obvious.
