Abstract :The European Modular System insert ignore into journalissuearticles values(EMS); is introduced to allow increased vehicle length and weight for road freight transport. Directive 96/53EC defines the types of combinations for this modular concept. This study concentrates on the Type-3 EMS so called `road train` including truck, dolly and semi-trailer combination. To get an idea about the effect of this long module combination over the valuable goods transportation, three cases are defined for the dolly`s front and rear suspension parameters, than 14-degree of freedom insert ignore into journalissuearticles values(DOF); half vehicle models are generated in order to observe the dynamic characteristics of the road-train for these three cases. Modal and transient analyses are performed and vertical displacement responses are obtained from front , middle and the end of the semi-trailer`s nodal points. Pitch angles of the semi-trailer body are also demonstrated. The change in the bounce responses and the pitch angles are interpreted for all three cases.
