| Abstract: | As the role of anti-skid brakes,the resonance phenomenon often occurs during aircraft braking and will leads to brake failure or the aircraft landing gear damage.The motions of aircraft landing gear and wheel in landing are analyzed.For the mechanism of resonance caused by the braking,from the perspective of the brake system,such as the runway identification,intelligent control technology,multi-level PBM technology,wheel speed acquisition and filtering,anti-vibration reinforcement,etc.,some effective means and measures to solve the vibration caused by braking are introduced.Some specific ideas to solve the practical problems are provided. |
| Keywords: | resonance aircraft brake control system gear walk |
