摘要:
为提高爆炸成型弹丸(EFP)的侵彻能力,采用AUTUDYN数值计算软件研究了内置敏感器件结构参数对EFP成型的影响规律,并通过典型末敏弹EFP战斗部侵彻靶板试验对计算模型的可靠性进行了验证。结果表明,敏感器件高度由0.15倍装药高度增加到0.50倍时,成型EFP速度增加1.29%,长径比减小30.9%;敏感器件直径由0.3倍装药直径增加到0.8倍装药直径时,成型EFP速度减小5.14%,长径比减小17.5%;随着敏感器件距起爆点距离由0.1倍装药高度增加到0.55倍时,成型后EFP的速度与长径比先减小后增加,且低值都出现在0.35倍装药高度处;对于阶梯形敏感器件,敏感器件直径比由0.4增加到1.0时,EFP速度减小3.2%,长径比增加39.1%;敏感器件高度比由0.4增加到1.0时,EFP速度减小4.2%,长径比增加38.4%。
Abstract:
To improving the penetration capability of EFP, the influence rule of structural parameters of built-in sensitive devices on EFP molding was studied by using AUTUDYN numerical calculation software, and the reliability of the calculation model was tested by the typical terminal sensitive projectile EFP warhead penetration target test. The results show that when the height of the sensitive device increases from 0.15 times the charge height to 0.50 times, the formed EFP speed increases by 1.29%, the aspect ratio decreases by 30.9%, and when the diameter of the sensor increases from 0.3 times the diameter of the charge to 0.8 times the diameter of the charge, the formed EFP speed reduces by 5.14%, and the aspect ratio decreases by 17.5%. When the distance from the starting point of the sensitive device increases from 0.1 times the charge height to 0.55 times, the speed and aspect ratio of the EFP after molding decreases first and then increases, and the low value appears at 0.35 time the charge height. For the stepped sensitive device, when the diameter ratio of the sensitive device increases from 0.4 to 1.0, the EFP speed decreases by 3.2%, and the aspect ratio increases by 39.1%. When the height ratio of sensor increases from 0.4 to 1.0, the EFP speed reduces by 4.2% and the aspect ratio increases by 38.4%.
