Modeling Of Vehicle Suspension System Using Bond Graphs

A great interest in active and semi-active suspensions has been arised, and that poses the problem of design a control system, and the first step is the modelling of the vehicle, its suspension, and its interaction with the guide-way. In this paper the multiport model approach and its associcited bond graph representation are suggested to perform the modelling task, since it can cope with a wide range of energy domains, offers clear and succint representation of systems and devices, allows an organized way to develop the system model and is suitable for development as a computer aided modelling software.
