| 摘 要： | 以直径为8mm的圆柱形破片为对象,采用非线性动力学程序AUTODYN,研究破片极限穿透速度与入射角度的变化规律。并用已有的经验公式验证比较,结果表明:破片入射角度越大,其变形越大,弹道极限速度也越大,且两者并非线性变化。在入射角小于45°时,仿真值与经验公式值基本吻合;在入射角大于45°时,两者误差较大,在入射角为60°时,两者误差达15.7%。当破片的入射角过大(大于75°)时,即使入射速度达4000m/s时,破片都不能贯穿靶板。

| Abstract: | In order to study the variation law of the limit penetration velocity and the incident angle,the cylindrical fragment penetrating the same target at different angle was simulated by the dynamic nonlinear process AUTODYN.The diameter of cylindrical fragment was 8 mm.The simulation value was compared to empirical value,it was found that as the incident angle of the fragment became larger,the deformation of the fragement was much larger and the limit penetration velocity was higher.The curve of the limit penet... |
