提出一种新型Tc复合弹结构,研究其对混凝土靶的开坑效果,利用LS-DYNA软件对该Tc复合弹的弹靶模型进行数值模拟,并进行了相关试验,最后与制式弹药的开坑效果进行对比。结果表明,Tc复合弹对混凝土靶的开坑效果明显优于制式弹。 A new type of Tc composite projectile was proposed to study its effect on the opening of concrete target. The LS-DYNA software was used to simulate the projectile target model of the Tc composite projectile, and the relevant experiments were carried out. Finally, The effect of contrast. The results show that the opening effect of Tc composite bomb on concrete target is obviously better than that of the conventional bomb.
