Aircraft landing gear system is a complex, multi-degree-freedom dynamic system. The braking process of aircraft wheels will produce dynamical response. When the vibration problem is serious, the braking performance will be affected, and even the flight safety of aircraft will be endangered. As for aircraft landing gear system dynamical characteristics, the axial and torsional brake dynamical models are set up based on the axial translational and rotational two degrees of freedom through stress analysis and reasonable simplify. The influence of friction coefficient change rate on vibration phenomenon is carried out and obtained. It has a certain reference significance to the principle of vibration in braking system and the improvement of vibration in braking process, and lays a foundation for subsequent improvement or elimination of aircraft brake system vibration phenomenon.
