The main landing gear is one of the important components in UAV aircraft. This paper aims to analyze natural frequency and determine its normal mode shape. analysis so that no resonance causes damage components. uses Aluminum 6061 material carried out using finite element method with help Ansys Workbench software. showed frequencies for 1 6 were 76.04 Hz, 85.07 167.82 201.92 288.39 327.00 respe...
