摘要

摘要: 应用AUTODYN-2D有限差分程序，对着速在0.6～2 km/s范围之间，不同材料、不同质量和不同长径比的长杆弹侵彻混凝土靶进行了仿真计算。分析了着速对侵彻深度和混凝土靶穿孔直径的影响。结果表明：混凝土靶穿孔直径随着速的增加而增大，但侵彻深度存在拐点。进一步研究了长杆弹材料、质量和长径比对侵彻深度拐点效应的影响，长杆弹材料对侵彻深度拐点的影响较大，长杆弹的质量和长径比对拐点的影响较小。

Abstract: Using the AUTODYN-2D software, penetrations of long-rod projectiles into semi-infinite concrete target at an impact speed of 0.6～2 km/s were simulated, in which materials, masses and length-to-diameter ratios of projectiles are different. The effects of impact speed on penetration depth and hole diameter were analyzed. The results show that hole diameter increases with the impact speed. There is a noticeable inflection point of penetration depth. The effect of material, mass and length-to-diameter ratio on inflection point of penetration depth was further studied. The material has a huge impact on inflection point of penetration depth, while mass and length-to-diameter ratio have a little impact on inflection point of penetration depth.
