研究了飞机平尾结构模型存在失调时的振动模态局部化及频率曲线转向现象.运用常规摄动理论分析了两现象的产生机理及规律,提出了一个判断准则。计算实例验证了分析所得的结论。
The vibration mode localization and frequency curve steering in the aircraft tail-tail structure model are studied. Using the conventional perturbation theory to analyze the mechanism and rule of the two phenomena and put forward a judgment criterion. The calculation example verifies the conclusion of the analysis.
