Landing Impact Load Analysis and Validation of a Civil Aircraft Nose Landing Gear
Aerospace, 2023 Landing impact load design is essential, but the process has rarely been fully described, and some designers have even neglected the differences between wheel-axle and ground-contact loads, as well as loads in the longitudinal direction, especially in ...

Bifurcation Analysis of a Coupled Nose-Landing-Gear–Fuselage System [PDF]
Journal of Aircraft, 2014 Under certain conditions during takeoff and landing, pilots may sometimes experience vibrations in the cockpit. Because the cockpit is located right above the nose landing gear, which is known to potentially be prone to self-excited vibrations at certain velocities, an explanation for those vibrations might be oscillations of the landing gear feeding ...

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.

Effect of Multi-Joint Clearance Coupling on Shimmy of Nose Landing Gear
Aerospace, 2023 The existence of joint clearances in the nose landing gear (NLG) is inevitable and significantly affects shimmy. It was found that the interaction of each joint clearance is closely related to the analysis of shimmy stability.

Aircraft Nose Landing Gear Shimmy with Nonlinear Tyre Models
International Journal of Bifurcation and ChaosIn this study, an application of a nonlinear tire model is considered in the analysis of aircraft nose landing gear shimmy. An aircraft single-wheel nose landing gear system is used to analyze the shimmy stability, where the tire model is designed to account the nonlinear relaxation length by the two-degree-of-freedom model, as well as the ...
