Abstract
Airborne photoelectric stabilization platform is an important tracking and scanning equipment. In order to make the photoelectric stabilization platform smaller and lighter, a four-claw spherical photoelectric stabilization platform is proposed. The four-claw spherical photoelectric stabilization platform is driven by piezoelectric motors with parallel structure. SolidWorks software is used to build the three-dimensional model of the stabilized platform. After reasonable simplification, the finite element model is built in ANSYS software. Comparing different mesh generation methods in the process of establishing finite element model, the mesh distortion is reduced from 0.74 to 0.38 by changing the mesh correlation and refinement. Different materials are used to design the platform, and the mass of the platform under different materials is compared. The platform mass of the new material is 30.3% and 66.4% less than that of the other two materials. The static characteristics of the platform with new materials are analyzed, and the maximum deformation and stress of the platform are analyzed. The results show that the designed airborne spherical photoelectric stabilized platform with new materials meets the requirements of stiffness and strength, which provides a reference for the design of such platform.
