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 ...
