引信离心力驱动垂直转子动力学模型

Dynamics Model of Fuze Centrifugal Force-driven Vertical Rotor

针对目前引信离心力驱动有轴垂直转子动力学分析不充分的问题,提出了考虑后坐力、哥氏力和章动力的转子绕定轴解除保险转动时的动力学模型,该模型运用矢量法分析了转子的受力情况。对榴-2引信的计算实例与理论分析表明,该模型更接近于实际,可以用于引信离心力驱动的有轴垂直转子的优化设计。

For the existing dynamics analysis for fuze centrifugal force-driven vertical rotor with axis was deficient,a model of applied force of rotor rotating round fixed axis was established,in which the effect of Coriolis force,recoil force and nutation force for rotor rotating was fully considered.And vector method was adopted to analyze the force of the rotor.Calculation examples and theoretical analysis showed that the model results was closer to the actual,which provideed theoretical support for the optimization design of the rotor.
