Thesis (M.A.S.)--University of Toronto (Canada), 2018.

This thesis evaluates the effect of two structural modifications to the performance of the landing gear shimmy damper developed by Safran Landing Systems. The dynamic model that features the two structural modifications was developed with necessary adjustments and validations. The effects are evaluated based on both eigen-value based steady-state stability analysis and the maximum amplitudes of the time responses generated with varying aircraft speed and random external loads applied to the landing gear tire during a simplified landing operation. The results have shown both structural modifications' effects regarding the shimmy damper's shimmy amplitude reduction performance and the recommended ranges of shimmy damper parameters values that result in effective shimmy suppression. The results also suggest that the recommended ranges for shimmy damper parameters are better to be determined based on the resulting maximum amplitudes of the time responses simulated with dynamic inputs than the dynamic model's eigen-value based steady-state stability.
