Over the past two decades there has been a great deal of research in the area of multibody dynamics and its application to the modelling of vehicles. Multibody dynamics formalisms can be categorized based upon several criteria. Of these, whether linear or non-linear equations-of-motion are generated by the technique in one of the most significant. In the Dynamics Laboratory in the Department of Mechanical Engineering at Queen's University both linear (A'GEM) and non-linear (REVS) programs for modelling road vehicles are used. In this paper the results from models of a 1/4 ton off-road vehicle (the ILtis) developed with A'GEM and REVS are compared with each other.
