通过对旋转弹丸外弹道角运动轨迹和攻角方程的理论分析,研究了以二圆运动模式为基础的弹丸运动矢量表示方法,进而将其分解为进动、章动和自转3个分运动。以二圆运动机械结构设计为依据,分别采用不同的机械结构实现了弹丸角运动的3个分运动,将3个分运动的机械结构合成后,完成了弹丸角运动模拟试验台的研制。最后利用动力学仿真软件Adams验证了弹丸外弹道角运动轨迹的正确性。

By theoretically analyzing angular motion and attacking equation of the rotating projectile in exterior trajectory, the vector expression of angular motion based on two circular movements was studied; the trajectory was broken down into bullets precession, nutation and rotation. The mechanical structure of three projectile motion was achieved according to this method, and combination of mechanical structure based on the three sub-movement was manufactured. Finally, the correctness of the model was verified by means of dynamic simulation software Adams.
