摘　　要：针对现有弹丸挤进模型计算量庞大,网格质量差的问题,提出了一种将身管和弹丸展平式的简化模型,并对不同动摩擦因数和不同坡膛角度的挤进过程进行了仿真分析研究。In view of the large calculation of the projectile-squeeze model and the poor quality of the grid,a simplified model was proposed to flatten the barrel and bullet to study the process of different friction coefficient and different angle of the bore.
