Design And Optimization Of A Novel Beam-Based Shimmy Damper

Abstract

Shimmy damper is a passive solution for undesirable oscillations in landing gears. Although it mitigates shimmy to an allowable degree, it can introduce weight, cost, and reliability penalties especially when retrofitted to existing gears. In this report, early investigations into a novel shimmy damper are presented. This damper is suitable for existing and new landing gears and is based on replacing a torque link member with a combination of springs and dampers to suppress the shimmy. The damper is then optimized
