The Modelica Multi-bond Graph Library

Bond graphs have established the~elves asa reliablefool for modeling physical systems. Multi-bonds are a bond graphic extension that provides a general approach to modeling all kinds of multi-dimensional processes in continuous physical systems. This paper presents; aiModelica Library for modehng.muiti-bond graphs and their application to three-dimensional mechanical systems. A set of bondgraphic models for ideal me-. chanical components is provided that enables a fully object-oriented modeling of mechanical systems ..The .. wrapping of the bond graphic models anatheir -representation by meaningful icons' gives the mechanical . models an intuitive appeal and makes them easy to.use. The resulting tnechanicai systems' can, be. efficiently simulated. Additionally, the continuous'~echanica:~.model~ were extended to hybrid models-that allow dis':'· crete changes to be modeled that occur. in. mechanical.system as.a-result of hard impacts.
