Multidisciplinary Modeling and Design of a Space Structure

Abstract

A method is needed to simultaneously integrate several engineering disciplines into one complete model to determine the performance of the system as a whole during the design development. System engineering methodologies are particularly suited to this problem. These methods provide a structured approach to problem formulation and system parameter identification. Bond graphs are also well suited as bond graphs model power flow and energy relationships within subsystems, a characteristic inherent to all dynamic systems. The intent of this research was to demonstrate the use of concurrent engineering theory to systematically model a large flexible space structure involving several engineering disciplines. The disciplines considered include: dynamics, controls, optics, structures, and heat transfer. A set of optimal solutions is presented and the results of this research are compared and contrasted with the results from classical design and modelling techniques.
