| Abstract: | As one of the main factors affecting the shimmy stability of aircraft in high speed gliding, the structural clearance of landing gear determines the safety and comfort of aircraft gliding. In this paper, the existing forms of landing gear structural clearance are summarized, and the formation reasons of landing gear structural clearance on shimmy are analyzed. The existing landing gear shimmy clearance analysis models are described in detail, and the limitations of the models and the future modeling direction are pointed out. Furthermore, the solving methods of the shimmy model with clearance are summarized, and the applicability of different methods is illustrated. Finally, the future research direction is prospected. |
