Abstract:

The interaction between braking and landing gear vibration is discussed, and the substantive causes of the vibration of landing gears are analysed. Among the parameters of the fore and aft stiffness of the landing gear strut, the rotary speed of the wheel, rolling radius, vibration cycle, predetermined slip ratio for the anti skid braking system and brake torque, a quantitative relation has been established. The goal is to try to solve the matching problem of the landing gear-wheel and brakes-anti skid braking system from the concetpt of viewing the situation as a whole, and to eliminate the vibration finally.

Key words: landing gear, brake, vibration
