In order to reduce production difficulties of fuze caused by the slender-booster structure, the output characteristics of boosters with different structures and different lengths were simulated by finite element simulation software ANSYS/LS-DYNA,and the pressure-time curves of each warhead’s point after explosion were obtained. The detonation ability of boosters with different structures and different lengths was judged by shock initiation theory. Results show that the booster with cumulative grooves exhibits stronger detonating ability and requires less booster charge, and its axial dimension is the shortest. The simulation was also verified by 39 initiation tests.%针对引信细长传爆管结构可生产性差的问题，应用有限元仿真软件ANSYS/LS-DYNA对不同结构和不同长度的传爆管输出特性进行了仿真，得到了不同结构和不同长度传爆管起爆后作用在战斗部炸药柱各点上的压力-时间历程曲线，并通过冲击起爆理论判断不同结构和不同长度传爆管的起爆能力。结果表明，输出端面带有聚能凹槽的传爆管相比于传统的平底传爆管，起爆能力较强，所需传爆药量少，轴向尺寸也最短。39发起爆试验验证了仿真可信性。
