Deployment Simulation of Ultra-lightweight Inflatable Structures
Dynamic deployment analyses of folded inflatable tubes are conducted to investigate modeling issues related to the deployment of solar sail booms. The analyses are necessary because ground tests include gravity effects and may poorly represent deployment in space. A control volume approach, available in the LS-DYNA nonlinear dynamic finite element code, and the ideal gas law are used to simulat...
متن کاملIn - ! Step Inflatable Antenna Description
Large size space deployable antenna structures are needed for a variety of applications. Current resources limitations within the antenna user community have resulted in the need for low cost, light weight and mechanically reliable space structures. An inflatable deployable antenna concept, under development at L’Garde has such great potential for satieing these requirements; it was selected fo...
متن کاملinvestigating 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...
An augmented Lagrangian optimization method for inflatable structures analysis problems
1. Abstract This paper describes the development of an augmented Lagrangian optimization method for the numerical simulation of the inflation process in the design of inflated space structures. Although the Newton-Raphson scheme has proved to be efficient for solving many non linear problems, it can lead to lacks of convergence when it is applied to the simulation of the inflation process. As a...
متن کاملToward Rigidization of Inflatable Structures
Active rigidization of a simple structure demonstrates how internal resistive heating can be applied to cause permanent physical strengthening of inflatable structures. Rigidizing a real structure brings to light the issues associated with incorporating the rigidizable resincoated tow onto a separate substrate and provides a useful example of the strength gained through effective rigidization. ...
