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.

起落架撞击期间起落架支腿沿飞机纵轴平面振荡的数值模拟

研究表明了在起落架载荷作用下飞机起落架在飞机轴向（齿轮-行走）的变形。提出了一种基于梁的模型来描述起落架的弹性特性和油撑杆的行为。对该模型进行了初步验证：找到了振荡的特征频率，并研究了系统在谐波负载下的行为。
