The research status of shimmy stability analysis and simulation of landing gear both here and abroad are summarized in this paper. The shimmy analysis model of civil aircraft nose landing gear is established, and the nose landing gear shimmy stability analysis program is compiled using MATLAB software the calculation is performed using the method of indeterminate complex number coefficient. Further more, the nose landing gear shimmy simulation model is established using the software Virtual Lab, and performed the simulation analysis using a certain aircraft parameter. These methods have been of great value of the guidance, practicality in the related programs.
