【摘要】：为得到聚能射流侵彻水夹层间隔靶规律,选取50 mm口径聚能装药对水夹层间隔靶(2 mm×4 mm钢靶板+100 mm水夹层)的侵彻过程进行了理论和实验研究。结合准定常侵彻理论和数学归纳法建立了射流侵彻水夹层间隔靶理论模型,得到了射流头部速度与侵彻距离之间的关系。为验证理论模型,用脉冲X光和计时仪获得了多个侵彻阶段的射流头部速度。通过模型分析了水夹层间隔靶结构对射流剩余头部速度的影响。结果表明:建立的理论模型正确,由其得到的射流穿过水夹层间隔靶后的剩余头部速度理论值与实验值平均误差为4.6%;当靶板厚度小于20 mm,且水夹层间隔小于150 mm时,水夹层间隔靶对射流头部速度的衰减效率较高。
[Abstract]:In order to obtain the law of penetration of shaped energy jet into water interlayer spacer target, the penetration process of 50 mm shaped charge was studied theoretically and experimentally on 2 mm 脳 4 mm steel target plate with 100 mm water intercalation.Based on the quasi-steady penetration theory and mathematical induction, a theoretical model of jet penetration into water interlayer spacers is established, and the relationship between the velocity of the jet head and the penetration distance is obtained.In order to verify the theoretical model, the jet head velocities in multiple penetration stages were obtained by pulse X-ray and timing instrument.The influence of interlayer spacer structure on the residual velocity of the jet is analyzed by the model.The results show that the theoretical model is correct, and the average error between the theoretical value of the residual head velocity and the experimental value is 4.6.The thickness of the target plate is less than 20mm and the interval of the water interlayer is less than 150mm.The velocity attenuation efficiency of water interlayer spacer target is higher than that of water intercalation target.
