| 摘 要： | 研究了弹载小尺寸装药侵彻混凝土靶板的冲击力学特性，将装药置于非惯性系中，其绝对加速度是牵连加速度与相对加速度的矢量和。利用应力波理论建立了小尺寸装药的相对过载方程，得到了装药的过载表达式，分析了装药相对过载与弹体相对过载的关系。对弹载装药侵彻混凝土靶板进行了仿真计算，得到了与理论分析一致的结果。为小型装药的侵彻过载特性评估提供了理论参考和分析方法。

| Abstract: | The impact characteristic of a small size charge carried by a projectile penetrating intoa concrete target was studied.In theoretic analysis model,the small size charge was set in a non-inertia cordinate system.The absolute acceleration of the charge was the vector sum of its transport acceleration and relative acceleration.Based on stress wave theory,a relative acceleration calculation model of the small size charge was presented in which the consistency condition in front of stress wave was utilized.The f... |
