Influence of Variable Side-Stay Geometry on the Shimmy Dynamics of an Aircraft Dual-Wheel Main Landing Gear [PDF]
, 2013 Commercial aircraft are designed to fly but also need to operate safely and efficiently as vehicles on the ground. During taxiing, take-off, and landing the landing gear must operate reliably over a wide range of forward velocities and vertical loads ...

Bifurcation analysis of nose landing gear shimmy with lateral and longitudinal bending [PDF]
, 2009 We develop and study 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 ...

Dynamic Fatigue Tests Of Landing Gears
Fatigue of Aircraft Structures, 2020 Landing gears are one of the main components of an aircraft. The landing gear is used not only during take-off and landing but also, in most cases, during ground manoeuvres.

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

A bifurcation study to guide the design of a landing gear with a combined uplock/downlock mechanism [PDF]
, 2014 This paper discusses the insights that a bifurcation analysis can provide when designing mechanisms. A model, in the form of a set of coupled steady-state equations, can be derived to describe the mechanism.

Oleo-pneumatic Mixed Shock Absorber Landing Pressure Analysis of Landing Gear
Hangkong gongcheng jinzhan, 2020 The landing gear of an aircraft bears a large impact load during landing, which causes the internal shock absorber to withstand high oil pressure and air pressure, and the buffer performance is greatly influenced.
