摘要/Abstract

摘要： 为提高杆式侵彻体的侵彻威力，设计了一种新的后置组合杆体结构。进行了相同外形结构的后置组合杆体与单一均质杆体垂直侵彻半无限钢靶的对比试验，试验结果表明，后置组合杆体侵彻能力优于均质杆体，侵深最大增加了25%. 通过数值仿真对后置组合杆体侵彻能力优于均质杆体的原因进行了分析，并与试验结果进行了比较验证。进一步数值模拟了4种不同配置的后置组合杆体在1 000~1 600 m/s着靶速度段侵彻半无限钢靶，得出了不同配置后置组合杆体的侵彻效率与着靶速度的对应关系。

Abstract: A new structure of post-composited rod is designed to improve the penetration ability of rod penetrator. The comparison experiment of post-composited rod and homogeneous rod with the same overall structure invertically penetrating a semi-infinite steel target is conducted. The result indicates that the penetration ability of post-composited rod is superior to that of homogeneous rod. The maximum penetration depth of post-composited rod is 25% more than that of homogeneous rod. The reason of the result is analyzed by the numerical simulation and verified by experimental result. The further simulation of post-composited rod with four different configurations in penetrating a semi-infinite steel target at impact velocity from 1 000 m/s to 1 600 m/s is carried out. The corresponding relationship between the penetration efficiency of post-composited rod with different configurations and the impact velocity is obtained.

Key words: ordnance science and technology, post-composited rod, homogeneous rod, penetration ability, configuration
