摘要
利用ANSYS/LS-DYNA软件对活性药型罩形成的射流特征进行了数值模拟,分析了药型罩不同形状、锥角及厚度对射流特征的影响;同时,通过实验对活性药型罩的毁伤性能进行了研究。实验结果表明:炸高条件为1.0D^1.5D时,破甲性能最佳,最大破甲深度可达65mm;活性药型罩形成的射流在击穿50mm厚度靶板后,可有效引燃靶后柴油箱。
The jet performance formed by reactive liner was simulated by ANSYS/LS-DYNA software,the influence of shape,cone angle and thickness of liner on the jet character was studied,meanwhile,the damage effect of the reactive liner was tested.The test results show that as the blasting height of1.0D^1.5D,the penetration effect is the best,the maximum penetration depth reaches to65mm,and the jet formed by reactive liner can penetrate the target plate with50mm thickness,then ignite the diesel oil tank effectively.
