Development of an Innovative Concept of Light Semi-Trailer By Means of FEM and Testing 2004-01-1517

A new light semi-trailer concept has been developed using numerical and experimental methods. In order to achieve this objective different types of light materials, such as high strength steels, aluminum alloys and sandwich compound materials, have been studied.

The different semi-trailer models have been studied by means of a numerical model simulation based on F.E.M. (Finite Element Method) and subjected to whole loads and various boundary conditions.

In testing whole strain values from critical points located in the semi-trailer have been obtained in order to correlate the numerical and the experimental results.

Finally, some of the initial semi-trailer parts and areas were optimized by means of numerical methods. Results obtained in the numerical simulations were applied to the analyzed structure in order to design a second generation of semi-trailer structure in which weight is decreased.
