中文摘要:
      设计了一种优化结构的薄壁高速侵彻弹体,采用YOUNG方程预估弹体高速侵彻钢筋混凝土的侵彻深度,通过建立三维有限元模型分析并计算了薄壁弹体高速侵彻2.4m和2.8m钢筋混凝土靶的能力和结构变形情况。在100mm口径的火炮上,开展了8kg弹体高速侵彻钢筋混凝土靶实验,考核了弹体的结构强度和侵彻能力。结果表明:薄壁弹体高速侵彻钢筋混凝土靶板后结构完整,在1020m/s和1200m/s速度下具备穿透2.4m和2.8m钢筋混凝土靶的能力。
英文摘要:
      A high speed penetrator with thin wall optimized structure was designed. The penetration depth in steel reinforced concrete of this projectile was preestimated by YOUNG equation. By means of three-dimensional finite element model, the penetration capability and structure deformation of this projectile were analyzed and calculated, under the condition of high speed penetration in steel reinforced concrete targets with 2.4m and 2.8m thickness respectively. Using 100mm caliber cannon, experiment of 8kg projectile high speed penetration in steel reinforced concrete target was carried out to evaluate its structural strength and penetration ability. Experimental results show that the projectile structure is still integral after high speed penetration in steel reinforced concrete target; this thin wall projectile has the ability to penetrate steel reinforced concrete targets with 2.4m and 2.8m at speed of 1020m/s and 1200m/s respectively.
