Impulse-bond Graphs

Keywords

Abstract

This paper presents a new supplemental tool for bondgraphic modeling, called the impulse-bond graph (IBG). These graphs are an extension of the classic bondgraphic notation and provide a proper way for describing discrete processes in physical systems. The Impulse-bond graphs are especially useful for modeling collision and transition processes in mechanical systems, but they can be applied to other domains as well. Modeling a system with the aid of IBGs is intuitive, since the IBG can be derived from the corresponding regular bond graph (BG) by applying a small number of fixed conversion rules. Hence, an experienced modeler can use his or her knowledge about classic bondgraphic models of continuous physical systems to create a corresponding IBG.
