动静不平衡度对旋转火箭弹散布影响的实验分析

THE TEST ANALYSIS OF AFFECTION OF SPIN ROCKET PROJECTILE′S UNBALANCE TO THE DISPERSION

利用旋转火箭弹动、静不平衡度的测试、修正及密集度试验，获得了动静不平衡度的分布规律、量值大小及其对该类火箭弹散布的影响规律．经过对实验结果的对比分析，证明了动静不平衡度都是影响旋转火箭弹散布的主要因素，并为今后的火箭弹设计。

The distribution law and dimension of spin rocket projectile′s unbalance and their effect law on rocket dispersion have been abtained through the unbalance measuring and correction of spin rocket projectile and filght testing of the rocket. By means of analysis of experiment results, it has been confirmed that dynamic and static unbalance are important factors that affect spin rocket projectile′s dispersion. This thesis also gives the suggestion to the design, manufacture and dispersion error analysis of rocket projectile.
