Simulation Analysis And Experimental Research Of Uav Composite Landing Gear

In this paper, the composite landing gears of UAV were carried out for key technology researches of statics, falling vibration and asymmetric landing, including the following:Firstly, the landing gears were carried out for computational analysis of statics research, and the deformation results of landing gear under different loads were calculated. The strength check result showed that the strength of the landing gears meets the needs of design. At last, the experimental study was carried on to verify the accuracy of the analysis results.In order to ensure the strength of landing gear meets the needs of UAV, the analysis and experiment of falling vibration were carried on, and the maximum deformation results of landing gear under different falling parameters were calculated. The result of strength check show the strength of landing gear meets the needs of UAV.Finally, the dynamics analysis was carried on to study the failure of landing gear caused by asymmetric landing in a UAV flight test, and the failure form of the landing gear was showed by strength check.
