Bifurcation Analysis of a Coupled Nose-Landing-Gear–Fuselage System [PDF]

open access: yesJournal 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 ...

Bifurcation Analysis of Nose-Landing-Gear Shimmy with Lateral and Longitudinal Bending [PDF]

open access: yesJournal of Aircraft, 2010
This work develops and studies a model of an aircraft nose landing gear with torsional, lateral, and longitudinal degrees of freedom. The corresponding three modes are coupled in a nonlinear fashion via the geometry of the landing gear in the presence of a nonzero rake angle, as well as via the nonlinear tire forces.

An Experimental Characterization on the Acoustic Performance of Forward/Rearward Retraction of a Nose Landing Gear

open access: yesInternational Journal of Aerospace Engineering, 2019
The modern undercarriage system of a large aircraft normally requires the landing gear to be retractable. The nose landing gear, installed in the front of the fuselage, is retracted either forward or rearward.

Simulation of Nose Landing Gear Shimmy with Flexible Airframe Considered [PDF]

open access: yesXibei Gongye Daxue Xuebao, 2018
Shimmy stability of the nose landing gear of an aircraft is studied in this paper. Firstly, Shimmy model was built considering the dynamic characteristics of the airframe. Then the critical damping, critical velocity and frequency range of the shimmy are

Dynamic Testing and Fatigue Analysis of the I-31P Nose Landing Gear [PDF]

open access: yesFatigue of Aircraft Structures, 2023
The landing gear is a critical safety component of any aircraft, playing a key role in managing the significant loads experienced during landing and ground maneuvers. In the case of the I-31P aircraft, a redesign of the I-23 landing gear system, required

Study on stiffness and shimmy stability of strut-type nose landing gear system

open access: yesHangkong gongcheng jinzhan, 2023
System stiffness (longitudinal, lateral, and torsional stiffness) is a meaningful index for strut nose landing gear design.It arises from profound significance to explore the influence law of system stiffness on shimmy stability for the anti-shimmy ...

Design and Analysis Aircraft Nose and Nose Landing Gear [PDF]

open access: yesJournal of Aeronautics & Aerospace Engineering, 2015
Tri-cycle arrangement landing gear is extensively used as it is simple; convenient both structurally as well as aerodynamically. Though it is advantageous over other configuration is has its own draw backs. Factors like its weight drag, sudden application of load, acoustics, fatigue etc tend to slow down its performance and life.

Bifurcation Analysis of a Nose Landing Gear System [PDF]

open access: yes15th Dynamics Specialists Conference, 2016
A methodology is proposed to enable the bifurcation analysis of a multi-body nose landing gear (NLG) model by coupling AUTO, a continuation software, to LMS Virtual.Lab Motion, a multi-body software. The approach uses a Singular Value Decomposition (or High Order Singular Value Decomposition) based technique to enable the computation of the stability ...

Shimmy analysis of light weight aircraft nose wheel landing gear [PDF]

open access: yes, 2022
This paper presents mathematical modeling and analysis of shimmy oscillations for a light weight airplane single wheel nose landing gear. Shimmy is a self-excited oscillation which occurs usually on the nose wheel landing gear assembly during ground ...
