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 usually be integrated fairly easily with today's modern digital computers. This thesis demonstrates a procedure for simulating the dynamics of a large inherently distributed structure using bond graph modeling techniques and incorporating a limited number of normal modes previously measured from an experimental modal analysis.
