从炸药装药的瞬时爆轰产物飞散理论出发,根据动量守恒原理得出药型罩装药形成爆炸成型弹丸的速度计算模型,并根据装药高度与直径之比对弹丸速度的影响修正了计算模型。应用该计算模型计算了大锥角药形罩和球缺药型罩装药形成的爆炸成型弹丸速度,计算结果与实验和数值模拟得到的结果吻合较好,此速度计算模型适合于工程应用。

设计了一种薄壁弹体,采用YOUNG方程预估该弹体侵彻混凝土靶板的侵彻深度,采用SAMPLL程序预估轴向过载。运用LS-DYNA软件分析弹体的侵彻过程,对材料力学性能进行实验研究。通过在Ø130 mm气炮上的一系列弹体侵彻钢筋混凝土靶实验,考核了弹体的结构强度和侵彻深度。结果表明:弹体在低速侵彻钢筋混凝土靶板时结构不会发生破坏,300 m/s速度下具备侵彻贯穿600 mm钢筋混凝土层的能力。

Parameter studies on impact in a lap joint

To represent a loose lap joint, a beam impacting four springs with gaps is modeled. Modal analysis with base excitation is solved, and time histories of contact points are closely monitored. Using the impulse during steady state response, six influential parameters are studied: damping ratio, contact stiffness, intermediate contact position, gap, excitation amplitude and beam height. For all parameters, the system response is highly controlled by modes with two contacting springs. Each parameter’s effect on system response is presented including unstable regions, unique trend behaviours result. Recommendations for structural designers are also noted.
