某型飞机颤振试飞中多种激励技术的综合应用与研究

Compositive application and investigation of many excitation techniques in flutter flight tests of X-type airplane

首先对颤振试飞所用激励技术进行了简单介绍。进而对某型飞机颤振试飞所选激励技术的原理进行了详细分析,并通过对该型飞机颤振试飞不同激励技术激励效果的分析讨论,给出针对该型飞机,多种激励技术补充使用所得激励效果明显的结论。最后对其它飞机颤振试飞激励方法的选用给出有益建议。

Here,the excitation techniques for airplane＇s flutter fight tests were introduced briefly. Then,the principle of the excitation techniques selected for X-type plane were analyzed in detail,and the conclusion that the excitation effect of compositive application of many excitation techniques in flutter flight tests of X-type plane is obvious was drawn through analyzing and discussing. At last,the useful suggestions were given for the choice of excitation techniques of other airplanes＇ flutter flight tests.
