Résumé
The purpose of this paper is to present a complete design study of foldable and unfoldable curved tensegrity systems with all the involved steps: generation of the curved tensegrity truss, implementation of finite mechanisms, structural analysis and folding/unfolding. Three criteria are required to introduce the finite mechanisms and self stress saving throughout the folding procedure. The new tensegrity configurations which meet these criteria are classified and illustrated with respect to three parameters: direction of truss beams, surface's mean curvatures and direction of articulation axes. Several configurations are then presented.
