Abstract :
The structure of micro-satellite is complex. Modeling and analysis of micro-satellite is necessary for structure design, which cannot only verify rationality of the structure design but also contribute to optimization design. Utilizing the software FEM (finite element method) MSC/Nastran, which is popularly used in international aerospace field, this paper models and takes dynamics analysis by taking a micro-satellite for example (named Sat X). The structure composing of Sat X is simplified properly by considering their function to the structure. The integrated FEM model is set up in Patran, premanager of Nastran. Static overload analysis and normal mode analysis is taken when Sat X is in launch condition
