Modelling complex vehicle systems using bond graphs (Q1073590)

In improving the performance of vehicles on the road, theoretical studies are needed which make use of dynamic models. This paper directs the attention to the use of the bond graph technique as an aid in modelling the physical system. Specific problems which may arise when the graph is prepared for the actual simulation phase are discussed. Advanced modelling including three-dimensional dynamics of coupled bodies and the multiple transformations needed to describe the system from engine via driveline, axle, stub-axle, wheel to tyre-road contact on possibly non- level road surfaces are treated.
