| Abstract: | The parameterized analysis model for a composite material central bearing column shell satellite platform was established using FEM software, and the analysis model for central composite column shell was then simplified according to the calculated vibration modes of the satellite platform. The central shell's structural optimization was performed under several design constraints, such as strength, displacement, vibration and buckling. Some design scenarios were calculated and compared, and the work done in this paper will be of reference value for structure design related. |
