Research on the Stability and Bifurcation Characteristics of a Landing Gear Shimming Dynamics System

Aerospace
A dynamic model is established to investigate the shimmy instability of a landing gear system, considering the influence of nonlinear damping. The stability criterion is utilized to determine the critical speed at which the landing gear system becomes ...
