小攻角条件下动能弹体高速侵彻混凝土靶的弹体弯曲

将高速侵彻混凝土靶板的弹体简化为自由梁,应用弹体侵彻阻力和梁动态弯曲内力分析了由小攻 角产生的横向载荷导致的弹体弯曲。结果表明,弹体理论弯曲条件受弹体着靶前状态、弹体结构和材料控制。 理论计算证实弹体高速侵彻混凝土靶板时由于小攻角的存在会发生弹体弯曲变形,弹体侵彻实验结果表明 弹体弯曲位置和弯曲条件与理论分析结果相符。

Bending of projectile with small angle of attack during high-speed penetration of concrete targets

The bending of the projectile in the process of high-speed penetrating concrete is studied by simplifying the projectile as a free-free beam.The bending moment caused by the transverse load which is generated from small angle of attack and penetration resistance is analyzed through theoretical work.The analysis showed that the theoretical bending condition is dominated by initial status,structure and material of the projectile.The computed results proved that the bending of high-speed penetrating projectile...
