BOND GRAPH TIME SIMULATIONS USING EXTRACTED MODAL PARAMETERS FROM THE NOVA SPACEFRAME

摘要

Bond graphs are a convenient way of representing the energy exchange, storage, and dissipation mechanisms for interacting energetic systems. One major advantage for using bond graphs to model physical systems is that the governing state equations are always in first order form and can be integrated fairly easily with todays modern digital computers. References [1] through [4] document bond graph physics and demonstrate the diverse applications for bond graph modeling The purpose of this paper is to demonstrate a procedure used to simulate a structure using bond graph modeling techniques that incorporate a limited number of normal modes previously measured from an experimental modal analysis.
