| 摘 要： | 本文通过对旋转火箭在光滑定向器内运动情况的全面分析,考虑到弹、炮之间由于间隙的存在,可能会出现“断续接触”的现象,从而抛弃了文献3]中“前、后定心部连续接触管壁”的基本假设,提出了膛内运动的分段解法,并利用所建立的“分段”模型对某弹的膛内运动姿态进行了计算机模拟,其结果与文献1]的实验比较符合。

| Abstract: | The motion of a spinning rocket inside a smoothbore laucher has drawn some attention in recent years. Xu Mingyou had studied thisproblem, took acount of the "tolerance" between launcher and rocket andestablished the model- "continuous tauching" model-describing the motion ofa spinning rocket inside a tube, which is not consistent with the experimentaldata in some imtial conditions. In this paper, an improved model- "continual touching" model-is given.And based on it, the computer-simulation of the motion of a certain spinningrocket inside launcher is made with succesful results compared with experim-ental results |
