| Abstract: | Deployable space masts are the fundamental deployable space structures to construct the large complex space structures.Ther esearch and applications of the different deployable space masts were investigated,and the comprehensive performances of the different structural forms were compared and analyzed.Additionally,the technical difficulties of the study and design of the deployable space masts were deeply analyzed based on the mechanics, material,space environment and vibration control considerations.Finally,the development trends of the deployable space masts were discussed in order to give necessary support to its design,selection and analysis in the future. |
