为了得出靶厚和着速对钢弹体PELE侵彻后效的影响规律,采用PELE实验弹以不同着速分别侵彻不同厚度钢板,并对后效靶上破片穿孔的数量和分布进行了分析。结果表明,在实验条件下,破片数量与着速和靶厚均有二次函数关系,破片飞散角与着速呈二次函数,但与靶厚呈线性减函数关系;着速对破片数量的影响要大于它对破片飞散角的影响;降低靶厚也利于增大破片飞散角。
In order to get the influence law of the target thickness and speed on the post-penetration of PELE, PELE experimental projectile was used to penetrate different thickness steel plates at different initial velocities, and the number and distribution of perforation on the target analysis. The results show that under the experimental conditions, the number of fragments has a quadratic function with the velocity and the target thickness. The scattering angle and the velocity of the fragment show a quadratic function, but it decreases linearly with the target thickness. The impact is greater than its impact on the fragment scattering angle; reduce the target thickness is also conducive to increasing the fragment scattering angle.
