摘　　要：对转管武器凸轮曲线槽机芯主滚轮进行动力学分析;根据圆柱凸轮双面约束的特点,分析了滚轮在曲线槽内的横越运动,以及约束面改变引起摩擦力方向改变时滚轮的运动情况;通过理论计算与仿真分析,研究了机芯主滚轮在曲线槽内的纯滚动、滑动和混合区范围及滚轮的转速和角加速度变化,研究结果可为转管武器凸轮结构优化设计提供依据。Based on the main roller system of the dynamics of the main roller of camshaft curve groove of Gatling gun movement was analyzed.According to the characteristics of the double-sided constraint of the cylindrical cam,the traverse movement of the roller in the curved groove and the movement of the roller when the direction of the friction caused by the change of the constraint surface were analyzed.The detailed theoretical calculation and simulation analysis were carried out.The range of pure rolling,sliding and mixing zone of the main roller of the movement in the curved groove and the change of the rotational speed and angular acceleration of the roller were studied.The result can provide basis for the structural optimization design of the runner cam weapon.
