3D ontwerp multi-trailer.
Report 99.3.TT.5150, Transport Engineering and Logistics.
As a solution for the traffic jam problems on the Dutch highways, the design
of a multi-trailer for use one public roads has been initiated. Trailer
combinations up to five times longer than usual will use the over-capacity of
the road-network at night.
Several studies related to this concept have been made. A steering system
that remains stable at higher speeds has been developed for already existing
Terminal-Multi-Trailers, the so-called Safe-Trail system. There has also
been a design study for the actual trailer. In this study the Safe-Trail
system was implemented and regulations for vehicles using public roads were
taken into consideration.
The 2-D drawings that were made for this design study are used in this
computer-assignment to make a 3-D model. Some of the dimensions are
parameterized in order to make easy adjustments in the model without losing
its internal structure.
The software package that was used for the 3-D modeling is called Mechanical
Desktop. This is a supplement of AutoCAD, a 2-D drawing program. Mechanical
Desktop was never used before in the Section of Materials Handling and
Transport Engineering. Therefor the other part of this computer assignment
was to explore Mechanical Desktop.
