摘要
主要研究了多项式拟合法在飞机颤振试飞数据处理中的应用技术,讨论了在数据预处理中应用指数窗对抑制噪声、提高数据处理结果精度的影响,最后提出了科学合理的数据处理方法,从而大大提高了试飞结果的准确性。
The application of polynomial fit algorithm was researched in the data process of the aircraft flutter flight test, and the influence of adopting the exponential window in the raw data processing to against noise and to enhance data processing accuracy was discussed. At last, the scientific and reasonable data processing methods were given, so that the flight test effects were greatly improved.
