为了研究章动运动对机械触发引信的影响,基于机械触发引信章动运动的相关理论,建立了机械触发引信对应不同章动角的虚拟样机,并对其进行动力学和运动学的联合仿真分析,得出了弹丸章动角速度在全弹道的衰减规律:上升段脉冲式递减,下降段趋于稳定;随着章动角增大,最大章动角速度和章动力递增. 研究结果表明,章动运动所产生的章动力会影响触发引信的击发. 得到的章动仿真数据和章动运行规律可以为机械触发引信抗章动能力的设计和零件选取提供依据和参考.

In order to research the influence of the nutation motion of fuse mechanical trigger, base on the correlation theory of the nutation of the mechanical fuse, establishes the projectile models of the mechanical fuse with different angles of nutation and carries on the analysis of dynamics and kinematics simula-tion. Through the simulation, obtain the angle velocity of nutation's law that descend in the ascending section and tend to be stable in decline period. With the nutation angle increasing, maximum nutation angle velocity and force increase. The result shows that nutation force will affect the fuse firing and the simu-lation date and change regulation can provide a basis and refer-ence for the design of the mechanical fuse against the force of nutation and the choose of part.
