Abstract:

Currently, the research on low-frequency braking coupling vibration of aircraft landing gear mainly is relatively lacking. In this paper a taxiing and braking analysis model for rigid-flexible coupling of two-wheel strut landing gear is established in the Simcenter 3D dynamics analysis software. The research results show that the vertical stiffness of the tire has a great influence on the vibration of the landing gear in the lateral and torsional. The vertical stiffness of the tire changes by 33% and the vibration in the lateral and torsional changes by about 5%. The cornering stiffness of the tire has a great influence on the vibration of the landing gear in the lateral. The cornering stiffness of the tire changes by 33% and the vibration in the lateral changes by about 15%.
