Abstract

Cargo
transportation is done by airway, railway, maritime line and highway according
to time and cost criteria. Trailers are widely used in highway transportation
which is one of these cargo transportation types. Depending on the amount and
variety of loads, the trailers vary among themselves. In addition to this
diversity, it is desirable that a trailer should be lightweight and at the same
time strong as far as transport safety and transport costs are concerned. When
all these factors come together, serious research and development activities
are required from the design stage to the final stage of manufacturing. One of
the R&D phases is computer aided engineering analyzing. Without requiring
material, labor and time, a design can be tested in virtual environment under
certain boundary conditions before physical validation. Crosses, which are the
one of the main carrier components in a trailer structure, between the longeron
(main beam) and the frame, that exist perpendicular to these components, has
been investigated in this study by taking into consideration of 1 g static
loading, 0.8 g braking and torsion scenarios. In this study, the essential
criteria are displacement and stress values of these crosses which have different geometries
(cross-sections). Comparisons were made according to the results and in the
light of these information, the finite element analysis results of the
combination of the chosen crosses to be used in the production of the trailers
were evaluated.
