The formability of EFP(Explosively Formed Projectile)in multi-functional warhead scheme was analyzed by using AUTODYN simulation software.Compared with the traditional layout program,the changed fragment scheme changes the deformation process of shaped charge liner and leads to the shape variation of EFP,thus reducing the penetrating performance.Through analyzing the structural parameters,the optimized solution was proposed to solve the shaping problem of EFP after the adjustment of fragment scheme.%应用AUTODYN仿真软件，对一种复合战斗部方案的爆炸成型弹丸成型性能进行了分析，结果表明，相对于传统布局方案，破片方案更改后改变了药型罩的成型过程，导致爆炸成型弹丸形状变差从而降低了毁伤性能。通过对结构参数影响进行分析，提出了优化方案，解决了破片方案调整后爆炸成型弹丸的成型问题。
