Numerical Simulation of Planar Oscillations of a Landing Gear Leg along the Longitudinal Axis of an Aircraft During the Landing Impact

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.
