摘要/Abstract

摘要： 分别制作了6组不同型式的靶体，进行了弹道侵彻试验研究，结合数值计算，确定了钢筋混凝土、钢纤维混凝土和钢纤维钢筋混凝土靶体的侵彻不贯穿系数(Kpp)，以合理确定混凝土靶体的侵彻不贯穿厚度(H);并定量分析了弹体侵彻深度（hp）及靶体背面支撑情况对(Kpp)的影响。研究结果表明，靶体材料及靶体背面支撑相同时，K pp随hp/d（弹径）的增大而减小；靶体背覆钢板对H的减小作用较小（不到5%），而靶体背覆砂土对H的减小作用比较明显（近20%）．

Abstract: The coefficients of the reinforced, the steel fibre and the steel fibre reinforced concrete tar?gets to prevent perforation (Kpp) were determined by combining the ballistic penetration experiments with the numerical calculation based on the six group targets prepared in different types, to determine thicknesses of the targets to prevent perforation (H) ; the influences of the projectile penetration depth (hp) and the support conditions in back of the targets on Kpp were analyzed quantitatively. The inves?tigated results show that for the targets with the same material and support condition in the back, Kpp decreases with the increasing of hp/d (caliber of the projectiles), and the steel plate on the back of the targets has little effect on H (less than 5% ) whereas the backfill soil on the back of the targets has ob?vious effect on H ( close to 20 % ).

Key words: mechanics of explosion , concrete target , ballistic experimentation , thickness of targets re?quired to prevent perforation , coefncients of targets to prevent perforation
