Abstract

Shimmy oscillations are undesired vibrations in aircraft landing gears. The onset of shimmy, marked by Hopf bifurcations, is investigated in the parameter space of an industrial, high-fidelity, flexible multibody landing gear model. The bifurcation analyses are performed by coupling the Virtual.Lab Motion multibody solver with the numerical continuation software AUTO. The resulting quasi-2-parameter bifurcation diagrams, involving aircraft velocity and vertical landing gear load, are verified using conventional time-domain simulations and are shown to guarantee significantly higher solution accuracy at a similar computational cost.
