Abstract

The European Modular System (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 (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.
