With the development of small unmanned aerial vehicles in different fields,the demand for stable platforms to cooperate with them is increasing,especially for the requirement of miniaturization and high precision.In this paper,a small photoelectric stabilization platform for small UAV is designed,which adopts the structure of two axes and two frames and applies modular design to the whole stabilization platform.The load can be replaced according to different requirements,and it has the characteristics of small size and light weight.Creo 3D software is used to model and Ansys simulation software is used to simulate and analyze the stiffness of the closed structure.The structural design meets the overall requirements.
