- Abstract
Micro-vibration response of satellite on orbit is different from that on ground test, and it is necessary to acquire micro-vibration response on orbit by simulation analysis using ground test data. In this paper, development and study of micro-vibration simulation analysis for small satellite is introduced, which uses the characteristic data of micro-vibration disturbance sources as analysis input, acquires displacements and angular displacements at key position by structural analysis, followed by image quality influence analysis. The small satellite’s micro-vibration simulation analysis system includes the module of micro-vibration test data analysis, the module of micro-vibration FE modelling and analysis, the module of micro-vibration calculation data analysis, and the module of imaging quality influence analysis induced by micro-vibration. The system can directly take micro-vibration acceleration test data, force and moment test data or angular displacement test data at key position into account, so it uses varieties of micro-vibration test data effectively, and improve reliability of micro-vibration analysis.
