“…We believe the proposed simulation method can be readily enhanced to study kirigami systems where patterns are non-continuous (e.g. [53,54]) and other similar folding-inspired systems. This model can enable the discovery of origami patterns that can be folded either by avoiding contact or despite self-contact, and can open up a new frontier for origami structures that harness contact to achieve new functionality.…”

Origami-inspired structures provide novel solutions to many engineering applications. The presence of self-contact within origami patterns has been difficult to simulate, yet it has significant implications for the foldability, kinematics and resulting mechanical properties of the final origami system. To open up the full potential of origami engineering, this paper presents an efficient numerical approach that simulates the panel contact in a generalized origami framework. The proposed panel contact model is based on the principle of stationary potential energy and assumes that the contact forces are conserved. The contact potential is formulated such that both the internal force vector and the stiffness matrix approach infinity as the distance between the contacting panel and node approaches zero. We use benchmark simulations to show that the model can correctly capture the kinematics and mechanics induced by contact. By tuning the model parameters accordingly, this methodology can simulate the thickness in origami. Practical examples are used to demonstrate the validity, efficiency and the broad applicability of the proposed model.

“…Deployable mechanism (DM) refers to a kind of mechanism that can be deployed from the folded configuration into the desired configuration in a specific manner. The ability of configuration change enables DMs to be widely applied to aerospace engineering, civil engineering, and medical equipment, such as space antennas and reflectors (You and Pellegrino, 1997;Song et al, 2017;Andrews et al, 2020;Ma et al, 2021), solar panels (Kuang et al, 2004;Kumar and Pellegrino, 2012), retractable rooftops (Kassabian et al, 1999;Delaney, 2014;Cai et al, 2019), and emergency shelters (Kiper et al, 2015;Cai et al, 2015). Large-scale DMs are usually constructed by assembling similar modules with specific connecting approaches.…”

Abstract. In this paper, an innovative cylindrical deployable mechanism (DM) based on rigid origami is presented, which is used to design a parabolic cylindrical deployable antenna. The mechanism can be deployed from the cuboid folded configuration to the cylindrical unfolded configuration with only one actuator. First, an innovative deployable string is proposed based on different types of four-vertices origami unit cells and kirigami techniques. By considering the units as 6R single-loop mechanisms, the kinematics of the origami unit cells are analyzed. Through the connection of identical deployable strings, the cylindrical DM is constructed, and its mobility is analyzed utilizing the screw theory. Then the proposed DM is used to design a parabolic cylindrical deployable antenna. A number of pillars are installed on the panels of the DM, and their lengths are determined to fit the required parabolic cylindrical surface. To verify the feasibility of the design, a scaled prototype of the deployable antenna is constructed.

“…So, in general, the parameter calculation process is rather cumbersome and time-consuming when the modified D-H method or the differential method is used for kinematics modeling of flexible arm. Meanwhile, Cai 27 studied the kinematic behavior of retractable kirigami roof structures, and presented a numerical method for kinematic path selection out of the singular point based on the higher order compatibility condition.…”

The cable-driven flexible arm based on the principle of origami is a new type of non-articulated compliant actuator with high integration, high environmental adaptability, large workspace/large deployment ratio. The forward/reverse kinematic models of joint space, operation space and driving space along with trajectory error model of the cable-driven flexible arm were proposed in this paper. The prototype of the flexible arm was developed capable of realizing bending, torsion and expansion/contraction. The simulation and experiment results of the cable-driven foldable flexible arm verified feasibility of the kinematic models and driving method proposed in this paper. Above research achievements lay necessary foundation for the next step to realize the key service functions of grasping/manipulation, three-dimensional precise movement, non-structural environment interaction/adaptation of the flexible arm with variable stiffness, variable configuration and variable size.
