Nose Landing Gear Shimmy Analysis with Variable System Stiffness Under Time-Varying Load

Aerospace
Vertical load fluctuations alter nose landing gear (NLG) system stiffness and complicate shimmy dynamics. Based on the full-scale NLG static stiffness test data, the relationship between shock absorber stroke and system stiffness was fitted, and a ...

Manufacture-oriented design of a topology-optimized nose landing gear fork for a small aircraft with retractable landing gear

CEAS Aeronautical Journal
Abstract Retractable landing gears are increasingly used in small and ultralight aircraft to increase range and cruising speeds by reducing aerodynamic drag. However, the available installation space for the landing gear is very limited. To make the best possible use of this space in terms of lightweight design and structural strength,

Evaluation of aircraft random vibration under roughness excitation during taxiing

International Journal of Transportation Science and Technology
The assessment of runway smoothness or roughness is intimately tied to the vibrational response of aircraft during taxiing. In this study, employing the pseudo excitation method (PEM) based on random vibration analysis, we unearthed the relationship ...
