摘  要:提出一种新型的预制应力槽的尖卵形头部结构,结合125 mm口径火炮发射工具,设计了仅头部结构有差异的25 kg级结构弹体。在800~900 m/s速度范围内,开展了两种头形结构的弹体侵彻4层间隔装甲钢板的实验研究和数值仿真分析。研究结果表明,提出的预制应力槽尖卵形头部弹体侵彻多层钢板的姿态偏转小于传统的尖卵形头部弹体,有利于在侵彻多层钢板过程中保持较稳定的姿态。In order to study the deflection attitude of projectile penetrating multi-layer steel plate at high speed,a new type of sharp oval nose structure with prefabricated stress groove was proposed.Combined with the 125 mm caliber gun launching tool,a 25 kg projectiles with different noses were designed.Within the penetration velocity ranged from 800 m/s to 900 m/s,the experimental comparative study and numerical simulation analysis of two kinds of nose shaped projectiles penetrating 4-layer interval armor plate were carried out.Based on the experimental and numerical results,the attitude deflection angle and structural damage of different structures noses were compared and analyzed.The results show that the attitude deflection of the proposed nose shaped projectile penetrating into multi-layer steel plate is smaller than that of the traditional one,which is beneficial to maintain a stable attitude in the process of penetrating multi-layer steel plate.
