doi:10.16182/j.issn1004731x.joss.19-FZ0352

Abstract

Abstract: The fight simulator with six-degree-of-freedom motion platform can simulate the flight attitude in real time and provide realistic overload dynamic feeling, which requires that the equipment on the platform must adapt to the overload during flight simulation. To solve the contradiction between the rigidity and weight of material, the glass fiber composite material is used to design and manufacture the spherical shell of the mirror . To improve the optical collimation of the reflector, the specific hyperboloid aspheric surface is selected as the surface design scheme,the 3D model of the spherical shell is constructed. The parameters of the composite materials are predicted based on the series and parallel models and empirical formulas of composite sheets. Aiming at the overload condition of flight simulation,the stress-strain finite element analysis of composite spherical shells is carried out by ANSYS software. The experimental results show that the structural design and material technology meet the engineering requirements.
