中文摘要:
      目的 评估覆钢板复杂结构的抗枪击性能,开展薄钢板抗枪击性能研究。方法 采用56式步枪人工发射方式,分别开展4、8 mm厚06Cr19Ni10单层钢板与8、16 mm厚30CrMoA单层钢板以及06Cr19Ni10与30CrMoA(4 mm+8 mm与8 mm+8 mm两种厚度组合)双层钢板抗7.62 mm普通弹的枪击试验,测量子弹着靶速度与穿靶余速,观测靶板的破坏模式,理论分析单层钢板的弹道极限速度。结果 7.62 mm普通弹不能穿透16 mm厚30CrMoA单层钢板以及所有参试双层钢板,其余参试单层钢板均能被穿透。基于Recht-Ipson模型,4、8 mm厚06Cr19Ni10与8 mm厚30CrMoA单层钢板弹道极限速度分别为511.7、498.6、684.3 m/s。结论 薄钢板随厚度的增加,破坏模式从韧性扩孔向塞块推出转变,均为韧性破坏模式。强度较高的背衬板有助于提高前钢板的抗侵彻性能。
英文摘要:
      The thin metallic plate is ordinarily used as rapped structure. The paper aims to evaluate the anti-penetration performance of the thin metallic plate against high-speed bullet, in order to evaluate the anti-penetration performance of the complex structure rapped by thin steel plate. The 7.62 mm bullet is adopted to evaluated the anti-penetration performance of thin metalllic plate, which is used by 56-type rifle manual firing method. Single steel plate, 4 mm and 8 mm 06Cr19Ni10 plate and 8 mm and 16 mm 30CrMoA plate are respectively shot by the bullet. Double steel plates, 06Cr19Ni10 and 30CrMoA plates with thickness combination as 4 mm+8 mm and 8 mm+8 mm are also studied. The striking and residual velocities of bullet is measured in the test, and the fracture mode of the target is analyzed. The ballistic limit velocity of perforated plate is theoretically obtained. It is indicated that the 7.62 mm ordinary bullet can not perforate the single steel plate made of 30CrMoA steel with thickness 16mm. It can not perforate all double steel plates tested in the present paper. Other single steel plates tested are perforated by the bullet. Based on the Recht-Ipson model, 4 mm and 8 mm 06Cr19Ni10 and 8 mm 30CrMoA steel plate has ballistic limit velocity 511.7 m/s, 498.6 m/s and 684.3 m/s, respectively. With the increase of thickness, the failure mode of plate transforms from ductile hole-enlargement into plugging, and both are ductile failure modes. The high-strength backing plate can enhance the anti-penetration performance of the front plate.
