Structure Design of Deployable Space Structures Considering Ground Test Evaluation

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Ultra-lightweight Deployable Space Structures

The ultra-lightweight construction of large, deployable space structures is a fundamental prerequisite for the realization of Solar Sail propulsion concepts. In addition to the functionality of the deployment technique and the development of control concepts, lightweight aspects and their technical implementation play a key role in future Solar Sail missions. A further development of the set-up...

Microdynamics and Thermal Snap Response of Deployable Space Structures

Effects of Multiple Structure-soil-structure Interactions Considering the Earthquake Waveform and Structures Elevation Effects

The simultaneous effects of soil and existing structures are known as the site-city interaction (structure-soil-structure). The impact of site-city interaction on structure behavior is effective. Thus, this interaction in some regions decreases the responses while increases in other areas. In addition, the site-city interaction of many parameters including the soil type, density rate, height of...

Deployable Soft Composite Structures

Deployable structure composed of smart materials based actuators can reconcile its inherently conflicting requirements of low mass, good shape adaptability, and high load-bearing capability. This work describes the fabrication of deployable structures using smart soft composite actuators combining a soft matrix with variable stiffness properties and hinge-like movement through a rigid skeleton....
