Shimmy Studies on Simplified Linear Nose-wheel Landing Gears Models
Journal of Aerospace Sciences and Technologies, 2023Multiplicity of parameters and complexity of various component models have made modelling and analysis of Landing gear dynamics a very complex task. This paper presents a study of shimmy instability on a simplified linear three degree-of-freedom model of a nose-wheel landing gear.

Shimmy Suppression Of An Aircraft Nose Landing Gear Using Torsional Nonlinear Energy Sink
Journal of Computational and Nonlinear Dynamics, 2023Shimmy motion may occur for an aircraft nose landing gear (NLG) during its take-off, landing and taxiing procedure, which is an undesirable motion and should be suppressed.

Failure analysis of a nose landing gear fork
Engineering Failure Analysis, 2017Abstract This paper presents a detailed analysis of a nose landing gear failure. The developed study comes following an accident occurred in which the nose of the landing gear's fork of a light aircraft failed during landing. According to Federal Aviation Administration, in average, 55% of aircraft failures occur during takeoff and landing. In order

Damping of the Shimmy Behavior in Nose Landing Gear System via PIR Controller
European Control Conference, 2023Shimmy is an oscillatory behavior that causes various accidents and malfunctions in the nose landing gear. This study has proposed a control method based on gamma stability due to damping the shimmy via the PIR (Proportional-Integral-Retarded) controller.

Aeroacoustic Study on a Simplified Nose Landing Gear
Applied Mechanics and Materials, 2012Simulation analysis and experiment research are performed on the aeroacoustic noise of a landing gear component in this paper. Detached Eddy Simulation (DES) is used to produce the flow field of the model. The Ffowcs-Williams/Hawkings (FW-H) equation is used to calculate the acoustic field.
