| 摘 要： | 基于对预埋主接头蜂窝板的静力与稳定性分析,对小卫星主接头进行选型优化。采用三明治夹心板理论建立预埋分叉式和面板式小卫星主结构连接接头的蜂窝板试件有限元模型,分析得到了蜂窝板最大应力值与失稳载荷,通过与试验结果的对比分析确定了蜂窝板试件破坏原因。在此基础上讨论结构参数对蜂窝板承载性能的影响,确定出最优的接头设计形式。

| Abstract: | The purpose of this paper is to study the type optimization of small satellite major joint,which is based on static and buckling analysis of honeycomb sandwich plates.Firstly the 3-D FEM model of honeycomb sandwich plates was established by the sandwich plate theory,in which the fork-form or faceplate major joint was buried beforehand.After the liner static and buckling analysis,the maximal Von-Mises stress and buckling load were obtained. Compared with the result of experiment,the failure causation to the Honeycomb Sandwich Plates was then determined.Finally the influence of the structural parameters upon load capacity was discussed,and the optimum major joint type was ascertained. |
