Abstract Origami has attracted more and attention due to its exotic mechanical properties, the inspired metamaterials are also popular. However, main focus of current research is on existing origami patterns although new or results that expand gradually emerging. In this paper, we summarize a series derived structures Kresling origami, demonstrating stable states richer structural forms. At same time, point-searching method proposed along ideas truss model, which effective for irregular these structures. On basis, create an origami-inspired metamaterial with foldable property high load-bearing capacity, fabricate prototype, validate performance through experiments. These works make important contributions promoting metamaterials.

Multi-function dual-layer origami metamaterials via bio-inspiration and multi-objective optimization

Mechanics of Advanced Materials and Structures, Год журнала: 2024, Номер unknown, С. 1 - 14

Опубликована: Ноя. 27, 2024

The mechanical advancement in conventional origami metamaterials is limited since only single layer exists at a deterministic scale. In this paper, the bio-inspired dual-layer (BDO) proposed, involving couple of nested layers connected by ribs. Sudoku-inspired surrogate models are developed for design parameters to tailor performance BDO. multi-objective optimization reveals that BDO exhibit superior compared with single-layer metamaterial strong interaction between ribs and layers. energy absorption capacity optimal improved 59.45%. Moreover, performance-oriented parameter selection system established, facilitating application wide range protective load-bearing scenarios.

Bio-inspired soft pneumatic actuator based on a kresling-like pattern with a rigid skeleton

Journal of Advanced Research, Год журнала: 2024, Номер 63, С. 91 - 102

Опубликована: Сен. 1, 2024

Biomimetic soft pneumatic actuators (SPA) with Kresling origami patterns have unique advantages over conventional rigid robots, owing to their adaptability and safety. Inspired by cloning moving behaviors observed from salps, we proposed an SPA based on a Kresling-like pattern skeleton. The elongation output force were tested, the effectiveness of applications was evaluated. consists skeletons skin. are constructed using layers patterns, while novel extensible inserting structure is devised replace folds found in patterns. This innovative approach ensures that exhibits axial contraction/expansion motion without any twisting movement. To mimic bionic characteristics swimming ingesting progress can perform contraction controllable bending multi-layered patterns; releasing life phenomena number changeable adding or reducing skeleton components according practical needs. experimental results multiple show increase above 162% layers; three-layer provide 6.36 N at air flow rate 10L/min, will continue as increases increases. Further, demonstrate grippers, scissor claw grippers pipe crawlers. Our avoid radial high force, guidance for bio-inspired robotic applications.

Abstract The performance and behavior of origami-inspired mechanical metamaterials are closely related to their structural design the joints sub equivalent crease, in addition material selection. Current research on square-twist origami focused unidirectional formation between its stable states. However, complete process squeezing-folding stretching-unfolding as well under tensile loading have not been thoroughly studied. In this study, (STOMMs) with soft proposed investigated. typical STOMMs from a flat state folded by extrusion folding then returning stretch unfolding is explored using finite element method. strain energy deformation characteristics revealed at eight special stages during folding, state, processes. Additionally, influence geometric parameters energy, deformation, also Finally, inspired chirality, combinatorial self-locking/non-self-locking validated for self-locking behavior. studies could provide new content joint terms load-bearing.
