Abstract: To design the light precision truss, which is fitted to characteristic of the light high resolution space camera, the method of mode analysis and the principles of designing the main truss are studied. The natural frequency and the first two vibration modes of different types supporting structure for the second mirror are analyzed using FEA software UG and Nastran.Then, a three vanes with triangular hub structure for supporting secondary mirror is proposed, and the design of the main truss is done. The analysis results indicate that the truss design has a higher resonance frequency and a light mass. So it can be applied to the light high resolution space telescope and it can also be a special reference to the design of other large aperture space telescope.
