“…Therefore, the objective of this paper is to provide the simplest possible numerical model which would allow quick changes upon the information acquired by the physical tests, and analysed through the method of redirected design [16]. With such an approach, we can make quick changes and achieve an optimized numerical model, verified by the prescribed method, with less time and less costs.…”

Bus rollover is one of the most analyzed cases of accidents, having in mind the number of potential large number of injuries and fatalities. Therefore, this type of traffic accident became the object of numerous national and international standards and regulations. The aim of this paper is to investigate the possibilities of experimental verification of presented simplified model of the bus body section. For that purpose, completely new multifunctional test bench was presented. The methodology applied for the experimental part was explained. The results provided by the numerical simulation and by the experiment were presented, and appropriate analyses were performed.The key parameters needed for the experimental verification were specified. According to the result analysis, a comparative results review was presented, confirming that the experimental verification of the numerical model was fully acceptable. Also, all of the requirements prescribed by the applied methodology for the achieved results acceptance were fulfilled, providing that numerical simulation, with constant improvements, could be a powerful tool for quick and reliable bus structure analysis in design process.
