Creating a Bond Graph model

Previous pageReturn to chapter overviewNext page

There are various methods described in literature to convert a ideal physical model into a bond graph. The simplest method is a direct conversion of the parts of the ideal physical model into bond graph elements. It is based on the fact that for every physical domain, junctions have a special interpretation. This allows us to make tables of ideal physical model parts and their direct representation as bond graph elements. The drawback of the method is that it is not generally applicable: for physical domains that are not described here, the user is referred to other methods.

1.Create an ideal physical model.
2.Replace each part of the ideal physical model with corresponding bond graph elements. Standard replacements are shown in the tables of this tutorial.
3.Select the bond graph elements in the 20-sim library and drag and drop them to the 20-sim editor.
4.Connect the elements according to the ideal physical model.
5.Simplify the bond graph according to the given rules.
6.Compile the bond graph model and run a simulation.
