摘要
介绍了回归分析方法在某飞行器尾翼颤振研究过程中的应用 .通过程序自动分析 ,使用检验方法 ,逐步获得与颤振裕度相关的频率因子 ,得到仅含有显著相关频率因子的最优回归方程 .分析表明 。
The regress analysis method is used in tail flutter computation. Through the automatic analysis, the frequency factors are gotten which are related to flutter margin, the optimizing equation is also obtained which is expressed by the remarked frequency factor. The analysis results show that the flutter margin regress equation meets the needs of engineering.
