The paper presents an application of an optimization procedure for a mass optimization of a welded framework of a special tractor trailer designed for transport of seeding machines. The used optimization procedure, so-called Fully Stressed Design (FSD), is based on an indirect approach utilizing optimum criteria. The aim of the optimization was to achieve the lowest possible mass of the construction taking into consideration the allowed resistance. As the paper shows, on the basis of the optimization procedure we achieved more than 35% savings of the material mass. In this way the optimization procedures have an important and unreplaceable role in practice, because they result in significant material savings keeping the required resistance and consistency parameters of constructions. For the resistance, consistency and optimization analyses there was used the programmed system Pro/MECHANICA in an integrated mode with CAD product Pro/ENGINEER.
