In this paper, development and study of micro-vibration simulation analysis for small satellites 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, following 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 modeling 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. 收起
