摘要
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 expres- sion 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 struc- ture based on the three sub-movement was manufactured. Finally, the correctness of the model was verified by means of dynamic simulation software Adams.
