Title:

Linear Stability Analysis, Dynamic Response, and Design of Shimmy Dampers for Main Landing Gears

Issue Date: Nov-2015
Abstract (summary): This thesis presents the linear stability analysis and dynamic response of shimmy dampers for main landing gears. The stability analysis is performed using a single tire landing gear model along with the dynamics of the shimmy dampers and the stretched string tire model. The dynamic response of each damper is obtained through a multibody model developed in MSC Adams and validated using existing literature. Two shimmy dampers are the focus of this study, one developed by Boeing and the other by UTC Aerospace systems. Finally, a new and improved shimmy damper is proposed showing the stability regions and its dynamic response. The proposed damper is lighter, easier to manufacture, to install, and to maintain, and has an overall better dynamic performance.
