摘　　要：利用有限元软件ANSYS建立复合材料中心承力筒式卫星平台结构的参数化有限元分析模型,计算了整星结构振动模态,在此基础上对复合材料蜂窝夹层中心承力筒结构分析模型进行简化,在满足结构的强度、变形、振动和屈曲约束条件下,对承力筒结构进行优化设计,并对多种方案进行比较,提出的方法和思路为今后同类结构设计提供了参考。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.
