“…Compressing and deploying the Kresling structure contracts or expands the scissor arms respectively and, as a result, changes the radiation pattern of the acoustic waves. Moshtaghzadeh et al [119,131,202] performed several comprehensive studies to analyze the structural stability and fatigue life of Kresling origami antennas. It was found that structure's stability under buckling loads improves by increasing the number of sides and reducing the height.…”

Structures inspired by the Kresling origami pattern have recently emerged as a foundation for building functional engineeringsystems with versatile characteristics that target niche applications spanning different technological fields. Their light weight,deployability, modularity, and customizability are a few of the key characteristics that continue to drive their implementationin robotics, aerospace structures, metamaterial and sensor design, switching, actuation, energy harvesting and absorption,and wireless communications, among many other examples. This work aims to perform a systematic review of the literatureto assess the potential of the Kresling origami springs as a structural component for engineering design keeping threeobjectives in mind: i) facilitating future research by summarizing and categorizing the current literature, ii) identifying the currentshortcomings and voids, and iii) proposing directions for future research to fill those voids.

“…The Kresling origami pattern was first introduced by Guest and Pellegrino, [1][2][3] whose research included geometric considerations, the folding process, and experiments related to the structure. This structure has since then been the subject of extensive theoretical research, including investigation of the stability behavior [4][5][6][7] and the influence of geometric, mechanical and material properties on the folding process. [8][9][10] In addition, reconfigurable properties of the origami have been explored [11,12] and it was shown that the Kresling origami is not rigidly foldable.…”

The study of multistable structures, particularly those that can twist, has attracted significant attention in recent years. This ability to transition between multiple stable geometries of these structures has paved the way for advances in diverse applications, such as morphing structures and robot actuation mechanisms. Conventional methods of designing and fabricating these structures often involve complex and resource‐intensive fabrication processes, which restrict their widespread adoption and limit their miniaturization. Here, we present a novel inflatable multistable twisting structure, based on helical folds of an elastic tube. Our fabrication approach utilizes directed mechanical instability as a method for a rapid fabrication, which is readily implemented at various length scales. We developed a theoretical model for the deformation of the bistable helical elements comprising the twisting structure, and compared it to experimental data. Furthermore, we demonstrate our fabrication methodology using a variety of polymers, including medical grade polymers, as well as various inner radii ranging from 5mm to 44μm and thicknesses of the tubes’ walls ranging from 250μm to 19μm .This article is protected by copyright.

“…Using the methods of isometric algorithm and compatibility principle, the outer ring has been set up to analyze the force density model according to the iteration of node positions and cable pretensions. Moshtaghzadeh et al (2021) proposed a reconfigurable antenna. The properties of the structure are investigated when its cross-section changes.…”

PurposeIn order to make the aperture of spatial deployable antenna larger, this paper proposed the study on a spatial annular tensegrity structure with 100 m large scale, which could be one of the ideal solutions to improve the dimension of the antenna. This study is aiming to figure out the dynamic characteristic of ultra-large annular tensegrity and address the problem of insufficient rigidity with local modes that many ring truss-type deployable antenna structures have faced.Design/methodology/approachThis work is carried out based on the nonlinear dynamic modelling when fully considering the effect of bending and torsion deformation of beams, as well as the pretension of cables. Additionally, the structural stability analysis based on the proposed stability criterion is also presented to evaluate the tensegrity configuration with different distribution of cable groups.FindingsThis research results verify that the modified structure with radial ribs could eliminate the effect of the local vibration mode on stiffness and is suitable to meet the requirements of the annular tensegrity structure. Additionally, the calculation results demonstrate that the structural configuration of annular tensegrity with 36 groups of cables which share the nodes with radial ribs is more appropriate to enhance the stiffness and structural stability.Originality/valueA new large annular tensegrity structure with radial ribs and tensioned cables is proposed. Based on the proposed structural configuration, the positive definiteness of the tangent stiffness matrix is carried out as the criterion of stability and the composition of the analytical expression of the tangent stiffness matrix is analyzed. Four levels of tensegrity structure stability have been carried out and the influence of the structural parameters on the stability and the rigidity has been analyzed. A scaled-down prototype is developed to verify the feasibility of the design of the hoop-column-rib configuration by the deployment and dynamic experiment.
