摘　　要：采用非线性动力学程序AUTODYN,分析不同板架结构形式对靶板吸能和弹体剩余速度的影响以及截锥形弹体不同初始速度下的剩余速度和靶板吸能情况,同时研究板架结构穿甲的力学机理和靶板的破坏模式。数值计算表明撞击点不同时横向加筋的大小对板架结构吸能影响不同,纵向加筋间距和大小的改变对板架结构形式的吸能效果影响不大,板体厚度越厚靶板的吸能效果愈好。不论撞击位置在何处,穿透靶板的弹体初始速度与剩余速度基本呈线性关系,且剩余速度相差不大。The non-liner transient dynamical software AutoDYN was used to analyze the effect of grillage structure pattern and initial velocity on absorbing capability of armor plates and residual velocity of shell. The armor piercing mechanism and failure mode of armor plates were studied. Numerical results showed that the size of lateral reinforced rib has different influences on absorbing capability of grillage under different impact positions. The size and spacing of longitudinal reinforced rib have little effects on absorbing energy. The thicker the width of plates is, the better the effect of absorbing energy is. The initial velocity of shell body which has pierced the armor plates is linear to residual velocity regardless of the residual velocity.
