This article summarizes the research status of landing gear stability analysis and shimmy simulation at home and abroad. The mathematic model of the front landing gear vibration analysis of large commercial aircraft is established. The stability analysis program of front wheel vibration is programmed by MATLAB software, and the complex parameter method is used to analyze and calculate. Using Virtual Lab software, the simulation model of the front landing gear shimmy is established, and the simulation and analysis of the parameters of a certain type of aircraft and the landing gear are carried out. It is of some guidance and application value to the landing gear vibration test.
