| Abstract: |
| The typical abnormal vibration of Fly-By-Wire aircraft is studied for the diagnosis and treatment technology. Firstly, the basic principle of aeroservoelasticity and the possible harm caused by aeroservoelasticity instability are introduced briefly. Then, the abnormal vibration phenomenon in the flight test of a Fly-By-Wire aircraft is described in detail. Through the comparative analysis on different types of data, the abnormal vibration is accurately located and diagnosed, and then the corresponding countermeasures are given. Finally, the accuracy of disposal measures is verified by the formal flight test. Through the treatment and analysis of the abnormal vibration in this paper, the root cause of the abnormal vibration is clarified. According to the effective implementation of the treatment measures proposed in this paper, the flutter/ASE flight test of this aircraft has been successfully completed. The research on abnormal vibration disposal method in this paper has produced useful reference for the accurate diagnosis and treatment of similar problems in the future. |
