摘要
常规药型罩在头部速度和延展连续性能方面存在发展瓶颈,侵彻深度无法满足要求。为了提高射流侵彻性能,设计一种新型柱-喇叭药型罩,并对其射流形成及侵彻过程开展试验与仿真研究。对比了药型罩形状对头尾部速度、射流形态及侵彻性能的影响,研究了不同曲率半径下的侵彻性能。结果表明:在相同圆柱部下,新型药型罩形成的射流在连续性上优于柱-锥和柱-球缺药型罩,其头部速度相比柱-锥药型罩和柱-球缺药型罩分别提高约12.26%、35.38%,侵彻深度提高约21.43%和39.06%,随着喇叭部分曲率半径的增大,射流头部速度增加,射流形态更加细长,开孔直径会随之增大。研究成果可为新型药型罩的结构设计及性能分析提供依据。
The development bottleneck exists in the head velocity and extended continuity performance of the conventional liner,and the depth of penetration cannot meet the requirements.In order to improve the penetration performance of the jet,this paper designs a new type of cylinder-horn liner,and carries out experimental and simulation studies on its jet formation and penetration process,compares the effects of the shape of the liner on the head and tail velocity,jet morphology and penetration performance,and investigates the penetration performance under different radii of curvature.The results show that in the same cylindrical part the jet formed by the new liner is better than the cylinder-cone and cylinder-spherical segment liners in terms of continuity,and its head velocity is increased by about 12.26%and 35.38%compared with the cylinder-cone and cylinder-spherical segment liners,respectively,and the depth of the penetration is increased by about 21.43%and 39.06%,and the head velocity of the jet is increased with the increase of the radius of curvature of the flared part,the jet morphology is more slender,and the aperture diameter increases.The research results can provide a basis for the structural design and performance analysis of the new liner.
