【摘要】：正六邊形鋼管約束混凝土靶具有優(yōu)良的抗侵徹性能。基于12.7 mm穿甲彈侵徹試驗(yàn),運(yùn)用ANASYS/LS-DYNA軟件,分析了正六邊形鋼管約束混凝土靶的鋼管壁厚和邊長對(duì)抗侵徹性能的影響;考慮效費(fèi)比,分析了鋼管約束混凝土靶的經(jīng)濟(jì)性能。結(jié)果表明:適當(dāng)增加鋼管壁厚和減小邊長可提高正六邊形鋼管約束混凝土靶的抗侵徹性能;優(yōu)化鋼管壁厚和邊長的匹配可以得到較好的抗侵徹能力和經(jīng)濟(jì)性,對(duì)于該文所用彈丸,較優(yōu)匹配為邊長37.5 mm、壁厚3.5 mm。研究結(jié)果可為鋼管約束混凝土遮彈結(jié)構(gòu)設(shè)計(jì)提供參考。
[Abstract]:The positive hexagonal steel tube confined concrete target has excellent penetration resistance. Based on the penetration test of 12.7 mm armor piercing projectile, the influence of the wall thickness and the length of the steel tube confined to the hexagon steel tube confined concrete target is analyzed by ANASYS/LS-DYNA software, and the economic performance of the steel tube confined concrete target is analyzed with the consideration of the effect. It is shown that the proper increase in the thickness of the steel tube and the reduction of the length of the side can improve the penetration resistance of the hexagonal steel tube confined concrete target; the optimization of the matching of the wall thickness and the length of the steel tube can get better anti penetration ability and economy. For the projectile used in this paper, the better match is 37.5 mm of the border length and the result of 3.5 mm. wall thickness can be used as the restrained coagulation of the steel tube. The structure design of earth shading provides reference.
