撞靶速度对活性破片释能规律的影响

Effect of Hitting Target Speed on Releasing Energy of Reactive Fragment

为了研究不同撞靶速度下活性破片的释能规律,测试了活性破片不同撞靶速度下的超压性能,计算了活性破片能量释放率,作出能量释放率与撞靶速度的关系曲线;测试了活性破片对多层靶的毁伤威力,计算了能量利用率,并作出能量利用率与撞靶速度的关系曲线。试验结果表明:随着撞靶速度的增加,该活性破片的超压值逐渐增大,能量释放率也逐渐增加;随着撞靶速度增加,该活性破片对多层靶累计毁伤面积逐渐增大,能量利用率也逐渐增大。

The releasing rate of reactive fragment energy was calculated based on the overpressure performance of reactive fragment under different hitting target speeds.The correlation between energy release rate and hitting target speed was also analyzed.The damage degrees of multilayer targets by reactive fragment were measured and the energy efficiency of reactive fragment was calculated.The correlation between energy efficiency and hitting target speed was also analyzed.The results show that the overpressure value of reactive fragment increases while its energy release rate decreases with increasing hitting target speed.The cumulative damage area of multilayer targets and the energy efficiency of reactive fragment both increase with increasing hitting target speed.
