| Abstract: | Aircraft landing gear shimmy seriously affects the comfort of occupants and service life of the body and landing gear,so landing gear wheel shimmy is one of the key issues of aircraft structural dynamics.In this paper,the initial theoretical basis of shimmy is described at first,and then the generating mechanism of shimmy and key factors to consider in prevention of shimmy design are elaborated.The overview of recent developments of shimmy studies is summarized,and the analysis and validation method of landing gear shimmy issue are presented in this paper from the view of engineering applications. |
