摘　　要：为了预测低面密度射流冲击反应装甲结果,利用理论手段推导了射流侵彻剩余速度公式并作出合理假设与u2d结合判定冲击结果,并利用仿真软件AUTODYN验证了假设的合理性和计算值的准确性。研究证明射流剩余速度在冲击起爆判定中可以准确预测。In order to predict the results of low-surface density jet impact armor,the formula of the jet penetration rate is deduced by theoretical means and the reasonable assumption is combined with u2 d to determine the impact result. The accuracy of the hypothesis and the accuracy of the calculated value are verified by the simulation software AUTODYN The The study shows that the residual velocity of the jet can play an accurate role in the determination of the impact initiation.
