战斗部头部形状对侵彻钢板影响的试验与理论研究

Experimental and theoretical research on influence of warhead's nose shape on penetrating steel plates

  • 摘要:
    目的 旨在探究战斗部头部形状对其侵彻匀质金属板性能的影响,
    方法 利用92 mm滑膛炮发射平头型战斗部、尖头型战斗部侵彻Q345B和921A 钢材料的靶板,通过测速靶网以及高速摄像方法对战斗部侵彻钢板前后的速度进行测量,分析侵彻靶板后战斗部与靶板的毁伤模式,从而建立起不同头部形状的战斗部侵彻下的理论评估方法。
    结果 结果表明:战斗部头部形状对侵彻靶板后的毁伤模式以及对不同类型钢板的等效换算都具有重要影响;尖头型战斗部对靶板的毁伤以花瓣型为主,平头型战斗部以剪切冲塞为主;与贝尔金公式相比,采用改进Thomoson公式计算战斗部侵彻靶板后的剩余速度所得结果与试验结果吻合更好。
    结论 所提方法及结果可用于后续对战斗部穿甲性能的评估,并可为后续大质量战斗部侵彻金属板研究提供相关依据。

     

    Abstract:
    Objective This paper aims to explore the influence of a warhead's nose shape on penetrating homogeneous metallic plates.
    Methods A series of armor-piercing penetration tests are performed by launching sharp and blunt-nosed projectiles from a 92-mm smoothbore gun to impact Q345B and 921A steel target plates. By recording the initial and residual velocity measurements of the warhead before and after penetrating into the target plates using a target net and high-speed video camera, the failure modes and damage modes related to the plates and projectile after the penetration test are analyzed, and an improved estimation method is established for calculating the residual velocity of the penetration of armor-piercing projectiles with different nose shapes.
    Results The results indicate that the warhead's nose shape has a significant impact on both the damage mode of the pierced plate and the conversion between various types of steel plate for the purpose of obtaining equivalent ballistic performance. In terms of damage characteristics, the petal failure of the target plate is the dominant mode after penetration by a sharp-nosed projectile, while a blunt-nosed projectile mainly contributes to the punching shear failure of the plate. In contrast with the K.A. Belkin formula for calculating the residual velocity of armor-piercing projectiles penetrating into plates, the proposed improved Thompson's formula in this paper is in better agreement with the test results.
    Conclusion The results show that the proposed method is adaptable to the similar estimation of armor-piercing projectile performance, thereby providing a basis for further research on the penetration of large-mass warheads into metallic plates.
