Deployable structures
… of describing the meaning and applications of deployable structures (making emphasis in the scissor-hinged and sliding mechanisms.) and the development of new geometries, details, and mechanisms that make these systems buildable and useful for architectural applications. A deployable structure …

Biomimetic deployable structures
… by virtue of temporary and convertible structures. Biomimetics is the applied science that, through the imitation of nature, finds the solution to human problems. By observing motions that occur in nature, for example, the blooming of a flower or the unfolding of wings, inspiration can …

Sliceforms: Deployable structures from interlocking slices
… of such sliceforms toward the design of novel deployable structures. A sliceform torus, composed of two sets of inclined slices arranged at regular intervals about a central axis of symmetry, has been discovered to exhibit a surprising and intriguing folding action whereby its incomplete form …

Deployable structures inspired by the origami art
… specifically for its application in designing a deployable structure. I analyzed its crease pattern, exploring variations and their corresponding folded forms. Simultaneously, different material ideas for larger-scale structures were tested and a particular configuration was assessed for internal …

Investigation of deployable structures and their actuation
Deployable Structures had not been designed for use in the oil field industry, and additionally have not been designed as devices to perform mechanical work. By analyzing deployable structures a detailed understanding of the mechanism kinematics has been developed. Further, we have analyzed new …

Polynomial continuation in the design of deployable structures
… continuation, especially in the field of deployable structure design. The power of polynomial continuation as a design tool lies in its ability to find all solutions of a system of polynomial equations (even positive dimensional solution sets). A linkage design problem posed in polynomial …

Shape memory alloy rotary actuator for CubeSat deployable structures
… any on-board hardware. Precision actuation of deployable structures has previously been achievable only through low SWaP single-use actuators or motor-driven, high SWaP multiple-use actuators. The Folded Lightweight Actuated Positioning System has the potential to provide an ultra-lightweight …

A rotary shape memory alloy actuator for CubeSat deployable structures
… increased power generation, and reconfigurable deployable structures. We propose using a shape memory alloy (SMA) actuator to meet this need. A SMA can be annealed at high temperatures to remember a trained shape. Upon cool down, the SMA element transforms to the martensite phase and is easily …

Development of rapidly deployable structures for military applications : a system based approach to command post facilities
… each component of a modern CP functions well, CP structures are slow to deploy because many of the components of the command structure are developed separately to fulfill specific functions. Separately, these components are quick and innovative. Combined, they are cumbersome and labor intensive to …

Design, analysis, and control of a nitinol shape memory alloy rotary actuator for spacecraft deployable structures
Small satellites known as CubeSats are becoming more and more popular in the aerospace industry and in academia. The new availability of rockets such as SpaceX's Falcon 9 or even dedicated CubeSat rockets such as Rocket Lab's Electron rocket have provided a new opportunity for many organizations to …

THE ART AND SCIENCE OF TRANSFORMABLE ARCHITECTURE: Geometry Theory for 2 Bar Scissor-Hinged and Expandable Origami-Scissor Hinged Deployable Structures
Deployable structures can transform and/or expand and contract due to their geometrical, material and mechanical properties. This technology enables an architecture that can be transportable, mobile, adaptable, rapidly built, reusable and that makes efficient use of space and materials and …

Analysis of deployable strut roof structures
Deployable structures are structures that can change shape from a compact to an expanded form. Thus, their advantage over conventional structures is adaptability, whether in the sense of adapting to changing environmental conditions or being adapted for repeated transportation and deployment. These …

Optimization of Tapered Deployable Space Structures
Modern spacecraft utilize deployable structures for many applications to strike a balance between functionality and size within a launch vehicle. Due to volume restrictions in a launch vehicle these deployable structures are stowed in a collapsed configuration during launch and deployed when the …
