| Summary |
In this study, we propose a method to stabilize large displacement behavior of membrane used for deployable structures, by incorporating elastic beams permitting large deformation. For the purpose to estimate the large displacement behavior of the hybrid structure, the membrane is modeled as unstable truss structure, and the elastic beams are modeled as series of rod members connected by rotational springs. After validating the analytical method numerically by using a simple structure, numerical calculations of retraction and deployment processes of a cylindrical membrane structure is executed. The results showed that the shape repeatability during retraction and deployment improved, by incorporating the elastic beams. Furthermore, it was found that the method could preliminarily estimate the state of membrane. |
