Paper Abstract

Space frame including satellite platform is the most important structure part in Space Solar Telescope (SST), which is designed to make observations of transient and steady state solar hydrodynamic and magnetohydrodynamic processes. This paper first introduces the space frame, which is not only a crucial linker between the optical and other subsystems but also a mechanical interface for the telescope and launching rocket. It must satisfy the optics with sufficient strength, stiffness, and thermal stability under the space environment and in the launching process. Then the author sets up finite element analysis model by MSC.Patran software and analyzes the mechanical quality under different load cases such as on-ground, during launching and in-orbit. In order to simulate the space environment and evaluate the influence of space heat to the whole space frame, the paper also presents space thermal calculation and analysis. Calculation results show that this space frame can meet the satellite’s requirements in space running. However, the thermal problem is still serious in primary mirror, which needs to be tested and controlled with strict way. Finally, the paper gives conclusions and forward suggestions, which will be applied to further research and fabrication in SST.
