| Abstract: | The dynamics of nose landing gear shimmy is studied in this paper with a certain type of aircraft.Based on the multi-body dynamics theory,a dynamics model of shimmy is developed which takes into consideration the flexibility of nose landing gear and airframe by means of the component mode synthesis method,to investigate the stability of shimmy.The model is verified with the data of static tests and mode tests.Diagrams of the stable region are presented accordingly,formed by the taxiing speed and critical an... |
