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。
A kind of thin-walled high-speed penetrating projectile with optimized structure was designed. The penetration depth of projectile penetrating into concrete was estimated by YOUNG equation. The three-dimensional finite element model was used to analyze and calculate the penetration of thin- m and 2.8m reinforced concrete target capacity and structural deformation. In 100mm caliber artillery, carried out 8kg projectile high-speed penetration of concrete target test to assess the structural strength of the projectile and penetration. The results show that the thin-wall projectile has a complete structure after penetrating into the reinforced concrete target at high speed and has the ability of penetrating 2.4m and 2.8m reinforced concrete targets at speeds of 1020m / s and 1200m / s.
