Abstract
Landing gear are a key structure in aircraft, not only supporting it on the ground, but also absorbing energy during landing, taxiing and braking. Due to the complexity of their construction, their dynamic behaviour is extremely complicated and the nonlinear response can result in the shimmy phenomenon. In this paper, several landing gear and tyre models are considered making use of a Virtual Lab Motion (VLM) multi-body analysis coupled with an AUTO bifurcation analysis in order to map the limit cycle oscillations (shimmy) with respect to changes in the system parameters; these results are compared with time integration results. It is shown that including the wheel dynamics in the stability analysis of the system and modelling the dynamics of the longitudinal tyre slip are essential in order to obtain accurate predictions.
