空间可展开结构拓扑综合方法研究

空间可展开结构的构型用邻接矩阵表示,采用拓扑变换的方法来研究空间可展开结构的拓扑综合.通过构件的增加、减少以及连接关系变化的变胞综合方法实现不同构型之间的变换运算.以周边桁架可展开大线结构为例,通过构型变换,得到了不同于目前同步展开/收拢方式的混合展开收拢方式,以及新的可展开结构的构型.通过所得类型的运动仿真,表明了混合展开方式以及新的可展开结构类型的可行性,验证了空间可展开结构拓扑综合的变胞综合方法.

Research on Methods of Topological Synthesis of Space Deployable Structure

The configuration of a space deployable structure is represented by adjacency matrix and the method of topological transformation is used to study the topological synthesis of the space deployable structure. The transformations among different con-figurations are implemented with the metamorphic synthesis methods of inereasing the members, decreasing the members and changing the connection. The hoop truss deployable antenna is taken as an example. Through the eonfignration transformations,the hybrid deployment is different with the synchronous deployment and the configurations of the new deployable structures are ob-tained. The motion simulations demonstrate the validities of the hybrid deployment, the configuration of new deployable structure and the topological synthesis methods of the deployable space structures.
