摘　　要：运用非线性动力学有限元软件LS-DYNA，开展了截锥形弹体在速度为0．6～2．3Ma范围的正穿甲和45°斜穿甲的数值模拟。靶板在弹体正撞击和低斜角撞击时，在各种速度下均为向前的花瓣型破坏。在高斜角低速撞击时，靶板出现向前的花瓣失效；在高斜角高速撞击时，靶板的花瓣部分向前，部分向后．其近着靶方向的花瓣向前，而远着靶方向的花瓣向后翻转。在不同速度下弹体斜侵彻靶板时，在较低速度下弹体在侵彻后其轴线与靶板的夹角增大，而在高速时其夹角减小。Based on the material mechanical behavior investigation of projectile and target, the process of truncated hollow projectile perpetrating thin steel target with oblique angle of 0°to 45° was simulated by LS-DYNA. The target plates fail because of ineffective petals. The configuration of target after penetration at high obliquity and low impact velocity is similar with that of normal impact. However, in the case of high obliquity and high impact velocity, the asymmetry deformation of the target and the projectile is exhibited.
