Abstract:
The study is presented of the aircraft landing gear deformations in the axial direction of the aircraft (gear-walk) under the load from a runway. Some beam-based model is proposed to describe the elastic properties of landing gear and the oleo strut behavior. The primary verification of the model is carried out: The characteristic frequencies of oscillations are found, and the behavior of the system under harmonic load is investigated.
