Deployment Study on a Single-Layer Deployable Truss Structure Driven by Elastic Components

The deployment analysis and test for a single-layer deployable truss structure driven by elastic component is conducted, aiming to design a flat deployable structure suitable for small satellites. The numerical model of components is built and assembled utilizing ADAMS, the software specialized for dynamics of multi-body system. The deployment of the deployable structure is simulated by means of numerical analysis. The dynamic performance of the deployment is investigated through the movement of joints of the structure. The 1.6 meter model was assembled and the deployment test was executed by means of method of non-contact measurement with high-speed cameras. The coordinates of the key joints during deployment were measured. The results of the measurement are compared with the results of numerical analysis.
