Simulation of Working Process of Force-1 A Fuze

为研究迫-1甲引信运动和作用过程,对其引信工作进行仿真模拟。使用多体系统动力学仿真软件MSC.ADAMS建立引信虚拟样机模型,模拟其运动过程并得到击针对针刺雷管的撞击动能;使用显式动力学仿真软件Ansys Workbench LS-DYNA对引信传爆序列爆轰作用过程进行仿真模拟,验证针刺雷管→导爆管→传爆管→主装药之间传爆的可靠性。仿真结果表明,该仿真模拟可为迫-1甲引信的改进或智能化改造提供数据支撑。

In order to study the movement process and action process of F–1 A fuze,the working process of the fuze was simulated.Using the multi-body system dynamics simulation software MSC ADAMS establishes the virtual prototype model of the fuze,simulates its movement process and obtains the impact kinetic energy against the needle detonator.Use the explicit dynamics simulation software Ansys Workbench LS-DYNA to simulate the detonation process of the fuse detonation transmission sequence,and verify the reliability of detonation transmission between the needle detonator→nonel→booster→main charge.The simulation results show that the simulation can provide data support for the improvement or intelligent transformation of F-1A fuze.
