摘　　要：根据短波与岩体的内摩擦模型,利用波阵面上的动量守恒关系和弹体表面的连续运动规律,得到岩体对弹体的侵彻阻抗;通过破碎区与径向裂缝区的能量传输关系,揭示侵彻与贯穿问题的比例尺度关系的规律,最后,推得弹体侵彻过程中的参数及侵彻深度计算新公式。通过现有的经验公式计算结果对比验证本公式的可靠性。According to the theory of short wave and internal friction model, the resistance of projectile is obtained from relationship of momentum conservation on the wavefront and continuum condition of the surface of projectile. The ratio scale relationship of penetration and perforation is revealed by the relationship energy transfer in the process of fragmentation zone to radial crack zone. A new generalized formula for calculating the penetration depth of non-deformable projectile is obtained from the projectile. The comparison between experiential formula results and the theoretical results verifies the validity of theory.
