在作者先前工作的基础上,进一步明确了适合于动能深侵彻弹的撞击函数和弹体几何函数的有效范围,可用于相关弹体结构的力学设计。同时从理论上研究了弹体的抗压/拉和抗弯能力,分别从抗压/拉和抗弯两方面来确定动能深侵彻弹弹体的极限壁厚。针对不同撞击速度的细长中空弹体斜侵彻混凝土靶,分析得到不出现弯曲破坏的弹体最大临界斜角和壳体壁厚下限,并给出弹体抗弯能力的最薄弱位置。对弹体的壳体厚度、局部加固和焊接位置提出建议。 Based on the previous work of the author, the author further clarified the effective range of impact function and projectile geometric function suitable for kinetic energy deep penetration projectile, which can be used in the mechanical design of related projectile structure. At the same time, the compression / pull and bending resistance of the projectile are studied theoretically, and the limit wall thickness of the projectile penetrating the projectile body is determined respectively from the aspects of compression / pull and bending resistance. According to the oblique penetration of concrete targets with slender hollow shells with different impact velocities, the maximum critical slant angles and shell wall thickness limits of the shells without bending damage were analyzed. The weakest positions of the shells were given. Propose shell body thickness, local reinforcement and welding position.
