| Abstract: | Vehicles are mobile structures. In vehicles, lightness, consumption efficiency, sustainability and safety are concepts that the European region attaches importance to [1]. Reducing the structural weight with the developing technology is one of the ways to reduce energy consumption and increase performance in vehicles [2]. In addition to the optimization between energy consumption and performance, structural strength and rigidity should not be ignored. Stability is more crucial when it comes to buses. Although driving assistant systems are being developed, fundamental properties of buses are still insufficient to some accident scenarios. One of the worst accident scenarios is rolling over. It is possible to make a design update on the vehicle in order to take precautions against roll-over. In order for the design update to be made, the boundary condition at the moment of the roll-over of the vehicle must be determined. Finite element method, which saves time and money, is a preferred method in many studies for determining boundary conditions. In this study, a roll-over simulation of a paratransit bus was carried out with the help of the finite element method according to the UN ECE R66 standard. The deformation results obtained at the end of the study and the deformation values in the structure were evaluated with the residual space criterion. At the same time, a section of real model of the vehicle was tested experimentally under the same boundary conditions. Experimental deformation results were compared with numerical simulation. In the results of this study, it was revealed that pillar D in the vehicle is the most critical part in the structure. The results obtained determined the focus point of the design improvement process. The results of this study revealed that the D-pillar in vehicle is the most critical part in the vehicle. The results obtained guided the design improvement process. |
