摘要
为分析弹丸倾斜入射不同间距硬目标的侵彻过载特征,运用ANSYS/LS-DYNA软件,对弹丸以不同初始速度倾斜侵彻不同间距的三层混凝土靶板的侵彻过程进行了模拟,获取了弹丸侵彻靶板的速度、加速度变化曲线.通过对不同着速弹丸的速度、加速度的变化情况进行分析,总结了其变化规律.分析结果可为以计层计空穴方式起爆的硬目标灵巧引信设计提供理论支撑,同时对抗高过载加速度传感器的选择也具有参考价值.
In order to study the overload characteristics of projectile aslant penetrating through hard target in different spacing,the article had made the simulation on the process where the projectile penetrates aslant through three-tier concrete target in different spacing by using the software named ANSYS/LS-DYNA,obtaining the curves which could reflect that how the penetrated velocity and acceleration changed.The rule can be found via analyzing the curves.The findings can provide a theoretical basis for designing hard target smart fuze which detonates by means of counting layers and holes,and a referential value for the selection of acceleration sensor which can be against the high overload.
