Abstract:
Each type of aircraft needs a unique landing gear with a specific structural system, which can complete demands described by unique characteristics associated with each aircraft. During landing of such a plain at first main gear touchdowns on two points and then, after several seconds, tire of the nose gear touches ground. The ground reaction acting on the landing gear is transmitted on the structure. When the aircraft lands, the force of impact is transmitted from the tyre to the axle. The paper discusses the methods used to the static analysis and presents model, which allow determining the dynamics characteristics of the landing gear. The dynamic analysis is important due to the shimmy vibration during the take off, which can cause collapse of the aircraft.
The numerical model of landing gear proposed by authors bases on mathematical model which was applied to obtain dynamic characteristic of chosen parts of the unit.
