| Abstract |
Deployable structures are space frames consisting of straight bars that are linked together into bundle and also are load bearing systems deployed largely. Deployable structures are easy to set up, to assemble, to disassemble, to transport and to keep for the use. Also, reusability and flexibility are another important advantages for environmental matter. Since deployable structures have various advantages, they offer viable alternatives for a wide range of potential applications in the temporary construction field as well as in the aerospace industry. The structural analysis of deployable structures involves two phases. The first phase in the deployed configuration under service loads is traightforward. In this case, we are able to apply linear analysis to analyse structures. But the second phase, analyzing the structure during deployment, is a much more complicated problem. Because large displacements occur, nonlinear analysis must be used for this case. Here is present to decide on geometrical parameters of the design through the numerical analysis and create a final configuration of deployable structures using the multi-body dynamic analysis. |
