Description
Summary:There is a wide application for the string-net structure in the areas of architecture and spaceflight. In the area of spaceflight, the string-net structure is mainly used in the deployable antenna. The three-dimensional string-net structure is a kind of typical string-net structures applied on the deployable antenna. Here the string-net structure is analyzed. At first, composition of the string-net structure is presented. Then the dynamical relaxation method is used to obtain the solution for movement of the structure after its instability. At last, using numerical simulation, tensions in the strings are computed. It is proved finally that the three-dimensional string-net structure still possesses the capability of keeping its shape and stiffness after its instability.
