The Dynamic Characteristics of a non-linear main landing gear system of an aircraft during landing [PDF]
Vibroengineering Procedia, 2020 The landing gear plays a very important role during landing by absorbing the high impact energy of the aircraft. The main landing gear absorbs the bulk of the load to reduce the load experienced by both the aircraft fuselage and the nose landing gear. In this paper, a mathematical approach is used to extract the dynamic characteristics of the system. A

Simulation analysis on semi-active control drop dynamics of whole aircraft landing gear
Hangkong gongcheng jinzhan, 2023 The application of semi-active control technology on landing gear is mostly limited to single or magnetorheological landing gear. The research on the whole aircraft is more valuable for the practical application of semi-active control.

Influence of Nose Landing Gear Torsional Damping on the Stability of Aircraft Taxiing Direction
Aerospace, 2022 The design of the nose landing gear (NLG) torsional damping is very important to avoid the taxiing vibration of the aircraft. On the one hand, increasing the torsional damping can suppress the nose wheel shimmy.
