长径比对长杆弹垂直侵彻能力影响机制的研究
Study on Effect Mechanism of Aspect Ratio for Vertical Penetration of a Long-Rod Projectile
摘要
Abstract
The penetration depth is analyzed for a long-rod projectile penetrating semi-infinite target using dimensional theory. Combining numerical simulation and empirical formula studies, the effect mechanism of aspect ratio is systematically investigated. The results show that the normalized energy density consumption by penetration depth increases as increasing of aspect ratio when the penetration efficiency does not change. For the long-rod penetrators with same volume, the penetration depth increases with the increasing of aspect ratio until reaches a maximum value. The main reason of this phenomenon is due to the funnel-shaped crater and high-temperature generated in subsequent unstable stage of penetration. The interface resistance effect has strong influence on the penetration depth, but which has no apparent connection with the aspect ratio of penetrator.关键词
