摘　　要：应用阶梯药型罩表面对称凹凸结构的方法可以研制出旋转稳定的自锻破片。利用有限元模拟软件和理论指导,对旋转自锻破片在三种不同的起爆载荷作用下弹丸成型过程进行模拟,再结合理论分析,对成型形状和弹丸速度进行分析。Spin-stabilized SFF can be made by surface symmetry concave convex structure of ladder liner method. Applying with finite element simulation software and theoretical guidance,The paper simulated the projectile molding process of spin SFF in three different initiation loads and analyzed molding shape and projectile velocity in theory.Some important data was obtained from this study which may be a reference for the existing or future experiments.
