Abstract: | In now days it is supposed that transportation has to fulfill two major tasks: an increasing volume and weight of the useful transported load with small costs, preserving in the same time the total weight of the transport ( truck and the transported wares). Theses two tasks can be in the same time accomplished on two ways: using for the heavy parts of the truck (engine, gearbox, chassis) new light materials which are in most cases more expensive, or by rebuilding them, through an optimization of the design. Using the numerical analyze program, that operation can be completed in only 30% of the time that is necessary using the traditional methods. In addition with simulation process, the costs are much diminished. |
