摘　　要：为研究几何参数对含能子弹侵彻过程的炸药响应影响,采用LS-DYNA软件对不同内外径比含能子弹侵彻铝合金靶板过程进行数值模拟,分析装药所受压力的变化规律。结果表明:侵彻过程中,装药前端首先达到炸药起爆压力并发生点火;随着装药直径的增加,头部装药压力峰值逐渐减小且达到峰值时间延迟,中后部压力峰值逐渐增大且达到峰值时间与头部趋于一致。对调整含能子弹装药起爆时间具有参考意义。In order to study of the geometric parameters of energetic explosive bullet pene-tration process response effects, the numerical simulation for different diameter of chargepenetrating aluminum alloy target process is undertaken by using LS-DYNA software, thevariation of pressure on the charge is analyzed. The results indicate that the fore of the ex-plosive charge mainly endures compressed effect to achieve detonation pressure firstly andthe ignition occurs. With the increase of the diameter of the charge, head Charge peak pres-sure decreases and reaching arrival time of peak pressure is rushed back. In central and pos-terior, peek pressure increases and arrival time of peak pressure closes to head. It is valuableto adjust energetic bullet detonating time.
