“…This vehicle, the dump trailer type and the object of analysis, basically consists of a steel box structure supported over a chassis linked to the driving cab through the front area of the king pin. The importance of this study is the optimisation of the box structure (Li et al, 2015). Figure 1 shows details of this type of vehicle: The box is composed of two lateral plates linked to another steel plate (box floor) strengthened by two jambs and some crosspieces.…”

The authors develop a new concept of dump trailer vehicle designed to carry arid materials, with a series of advantages and improvements with regard to equivalent structures. For this reason, design criteria and objectives that must have been carried out in executing different stages to reach the final 'optimum' vehicle have been taken into account. From a detailed study of previous performances for this type of vehicle, it is intended to reach a series of objectives involving redesign and modification. That is the structural lightering and changes must mean the improvement of structural performances, both in terms of rigidity and endurance. The improvement of these variables will make possible the launch of a new product incorporating an improvement over current models. Moreover, the inclusion of sandwich structures in the design of the dump box's floor and door supposes a great novelty, intended to achieve significant weight saving.

The combination of safety belts and rollover protective structures (ROPSs) is key in improving the safety of agricultural tractors in the event of rollover. However, we also have the opportunity to enhance the security provided by each ROPS; one such example is the combination of this safety device with adequate mechanical energy absorbers (MEAs). Inexpensive disc-shaped MEAs can be included in the anchoring points of a ROPS onto the chassis of a tractor. Three configurations of ROPS combined with MEAs were tested during the application of loads that simulated the effects of side rollover in the vehicle. The tested configurations included a blank MEA as a reference case alongside a single MEA and a stack assembly containing both elements. The results of the tests show that both the deformation of the ROPS itself and the strain energy are larger in the case of blank MEAs; thus, there is also a risk that the clearance zone will be infringed upon and that the protective structure will collapse. We can conclude that the implementation of an appropriate MEA in ROPS reduces the deformation of the ROPS itself and its strain energy in cases of vehicle rollover; hence, the safety provided by such protection systems may be improved at a low cost.
