随机因素对弹丸起始扰动影响的分析方法

A METHOD TO STUDY RANDOM FACTOR'S EFFECTIONS ON INITIAL DISTURBANCE OF PROJECTILE

用均匀设计方法通过回归分析来研究随机因素对起始扰动的影响 ,可以得到影响起始扰动的主要因素及其影响程度 ,并能得到起始扰动的标准差 .

In this paper, the affecting of random factors to initial disturbance of projectile is studied by using uniform design and regression analysis, the main affecting factors and their influence degree can be found through this method, and the standard deviation can be calculated also. Comparing with test results proves that this method is reasonable.
