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 bounds (e.g. the onset of shimmy) in a very efficient manner. Sensitivity and uncertainty analyses are performed to determine the influence of various structural parameters on the onset of shimmy. A representative aircraft landing gear model was used to validate the approach and it was demonstrated that a good comparison with full-scale Monte-Carlo time simulations was achieved with a much reduced computational expense.
