Abstract
Bond graphs have established themselves as a reliable tool for modeling
physical systems. Multi-bonds are a bondgraphic extension that provides
a general approach to modeling all kinds of multi-dimensional
processes in continuous physical systems. This paper presents a Modelica
library for modeling multi-bond graphs and their application to
three-dimensional mechanical systems. A set of bondgraphic models
for ideal mechanical components is provided that enables a fully
object-oriented modeling of mechanical systems. The wrapping of the
bondgraphic models and their representation by meaningful icons
gives the mechanical models an intuitive appeal and makes them easy
to use. The resulting mechanical systems can be efficiently simulated.
Additionally, the continuous mechanical models were extended to
hybrid models that allow discrete changes to be modeled that occur in
mechanical system as a result of hard impacts.
