Optimization Design and Modal Analysis of Satellite SAR Deployable Support Structure

Abstract:

The design flow of deployable support structures is proposed based on modal analysis, and the finite element model for DST of satellite SAR is researched. On these bases, the affecting factors of DST attitude fundamental frequency (f₁) and mass, such as geometry parameters, the lock position, stiffness of hinges and thickness of truss links, are analyzed and optimized. Lastly, considering of space thermal environment the optimal design of the DST is meted the requirements under different thermal fields. The research results are of great importance to improve the performances of DST.
