The finite element simulation analysis of the solar sail structure is studied. According to the actual structural characteristics of the solar sail spacecraft, a reasonable finite element model is established; the size and direction of the reasonable boundary pre-tightening force are obtained; Prestressing buckling modal analysis and buckling critical load. The non-prestressed structure modal analysis of solar sail structure and modal analysis of pre-stressed structure are carried out and the results are compared. The results show that the solar sail Spacecraft pre-tightening force modal analysis is more reasonable, which provides a reference data foundation for the design and simulation of solar sail spacecraft control system engineering.
