| Abstract: | Based on the advantages of light weight,small stowage,and high reliability of deployment,the coilable lattice mast can be applied on the deployment of large solar array and large antenna structures.Used as the main deploying and supporting members,the lattice masts play an important part on the whole space structure.According to the design and manufacture of a coilabe lattice mast,the construction details,design concept,and principle of deployment and fold were described.In addition,the geometric design parameters were also analyzed.The stiffness analysis was investigated with the geometric relations of deployment and stowage.And the local and whole stability analyses were also studied with stability theory.These analyses provide an important role on the development and a key technology of this coilable lattice mast. |
