Abstract: Aiming at the problem that the traditional UVA stabilized platform had higher load and poor structural stability which was difficult to obtain aerial image information with high stability at low altitude, the principle of attitude compensation and displacement regulation on stabilized platform system was expounded, the selection of the material, the design and assembly of the main structure, the loading position and loading application of the stabilized platform were studied. A small three axis symmetrical stabilized platform for Multi rotor UAV was designed, which had considered the lightweight, easy to assemble and good workability in the goal orientation. Meanwhile, the static and modal analysis of the stabilized platform model was carried out by using the finite element analysis software—ANSYS Workbench, and also the corresponding simulation data were extracted. The results indicate that this design has good function and reliability in strength, stiffness and damping capacity, which can make sure the camera will compensate for the displacement and vibration in aerial photography and realize the function of image stabilization.
