摘要:
借助ANSYS/LS-DYNA软件对线型聚能切割器水下切割钢板性能的影响因素进行了数值模拟研究。重点分析了水介质、有无药型罩和带有空气槽对射流侵彻靶板的特性影响。结果表明：聚能槽内的水介质会阻碍射流的形成，严重影响切割性能；带有空气槽的切割器可以提供射流形成的空间，大幅提高射流的侵彻能力；通过对无药型罩切割器水下切割钢板的数值计算，得到的钢板侵彻深度可达15.3 mm，相比有药型罩时，无药型罩的切割深度有了很大提高，侵彻深度大约是有药型罩的3倍，接近空气中线型聚能切割器对钢板的切割深度17.2 mm。
Abstract:
ANSYS/LS-DYNA was used to simulate influence factors on underwater plate cutting performance of linear shaped charge cutter. Effects of water, liner and air groove on cutting plate properties were mainly analyzed.Numerical simulation results indicate that the water in shaped groove would hinder the formation of jets and affect the cutting performance greatly; cutter with air tank can provide jet formation space and improve the penetration ability of jet greatly. Penetration depth is confirmed as 15.3 mm based on numerical calculation of underwater steel plate cutting by no-liner cutter,and cutting depth have greatly improved compared to that formed by liner cutter. Penetration depth by no-liner cutter is three times of that by liner cutter, and its cutting depth is close to 17.2 mm achieved by linear charge cutter in air.
