| 摘 要： | 为了改善高射速转管炮自动机的动力学性能,基于正弦型加速度凸轮曲线设计理论,运用五次多项式替代正弦型加速度规律对曲线槽过渡段进行优化设计,并基于MATLAB软件计算出优化后的凸轮曲线槽理论方程。然后利用ADAMS建立6管转管炮自动机虚拟样机模型,模拟其在6 000发/min的射频下的动力学性能。计算结果表明,滚轮与凸轮曲线槽间的接触力平均降低了1.15 k N,同时机芯组加速度平均降低了105 m/s2,转管炮自动机的动力学性能也得到显著改善。

| Abstract: | In order to improve the dynamic performance of the automaton for high fire rate Gatling gun, based on the design theory of sine acceleration cam curve, the optimal design of the transition section of curve groove is achieved by using the five degree polynomial instead of the rule of motion of sine acceleration. And based on the MATLAB software, the optimized theoretical equation of the cam curve groove is calculated. Then, the virtual prototype model of 6 tube Gatling gun is established through ADAMS with the dynamic properties of the model simulated in the radio frequency of 6 000 r/min. The calculation results show that the contact force between the rolling wheel and the cam curve groove is reduced by an average of 1.15 kN. Besides, the acceleration of bolt group is reduced by an average of 105 m/s2 with the dynamic performance of the automaton in the Gatling gun improved greatly. |
