Improved Landing Gear Shimmy Model

This report introduces a new conceptual model to study aircraft landing gear shimmy (LG-Shimmy). The new formulation offers the engineering analysts an improved LG representation allowing better ability to capture aircraft landing gear shimmy behaviour. The improved model is introduced along with two historical models common in the analysis of shimmy. Parameter values are presented to populate the models, and a verification review is performed. The benefits of the improved model are highlighted.
