The work shows the use of bond graph formalism for modeling dynamic systems. According to the consideration of energy flows in an engineering system, the vertices of a bond graph denote conceptual subsystems, system components or elements, while the edges, called power bonds or bonds for short, represent energy flows between them. A more detailed model would include a tire model, and damper nonlinearities such as velocitydependent damping with greater damping during rebound than compression.
