“…The mobility of foldable plate linkages can be determined from the layout of the plates. For all patterns similar to pattern A from Fig 2 the total number of degrees of freedom is p+2m+2 as shown by Foster [1]. When used for patterns similar to B the formula becomes p+2m+4.…”

“…These consist of a series of triangular plates, connected at their edges by continuous joints, allowing each plate to rotate relative to its neighbouring plate. The plates can fold into a flat stack and unfold into a predetermined threedimensional configuration, as the one shown in Fig 1. The geometry of these structures has been discussed by Foster [1] and Tonon [2] who have proposed a variety of shapes such as beams, barrel vaults and doubly curved surfaces. However, not all configurations are foldable: some are merely demountable while others are constructed from smaller foldable sub-structures that have to be joined together afterwards.…”

A concept for a mobile shelter is proposed, based on the geometry and kinematic behaviour of foldable plate structures. The folding pattern and the associated design parameters are discussed, along with their influence on the geometry and the kinematic behaviour. It is shown that the transition can be made from a foldable plate structure to a foldable bar structure, while retaining an identical kinematic behaviour. This is done by introducing custom-built joints for connecting the bars which allow the system to deploy in the desired way, maintaining the same D.O.F (degree of freedom) as the plate system. For the structure to be employable as a fully-fledged temporary space enclosure, a lightweight textile membrane is incorporated beforehand and deployed along with the bar structure.

“…The best way to understand the background of this problem is to consider the case of post-ASME © buckling behavior of a thin cylindrical shell under axial loading. A family of foldable, portable structures, based on the Yoshimura origami pattern, has been presented by Foster and Krishnakumar [14]. These structures have considerable shape flexibility (multiple degrees of freedom), but once erected they possess significant stiffness.…”

This paper investigates the geometry of a foldable barrel vault with Yoshimura Origami patterns during the motion. On the base of the geometry analysis of the origami unit, the radius, span, rise, and longitudinal length of the foldable barrel vault with regular Yoshimura Origami pattern in all configurations throughout the motion are determined. The results show that the radius of curvature and the span increase during deployment. But the rise increases first, followed by a decrease with increasing fold angle. Furthermore, the influence of the apex angle of the origami unit and the numbers of triangular plates in the span direction on the geometric parameters is also investigated. Finally, the method to obtain the rise and span of the barrel vault with irregular origami pattern is also given.

The paper is a critical review of different structural systems that have been proposed to date for the purpose of deployable space enclosure. The structural systems are classified by their morphological and kinematic characteristics, and comparatively evaluated in terms of their structural efficiency, technical complexity and deployment/stowage efficiencies. Although the main focus is on kinematically deployable structures, some retractable and dismountable configurations are also reviewed. The paper includes an extended list of references.
