“…On the basis of the performed study, it can be concluded that the finite-element simulation of bus rollover considering bus rotation process coincides with the experimental data. It is worth to underline that there is a computer simulation approach, where the bus model turns into the contact position with the ditch surface at the initial time of the simulation, and the angular velocity is assigned to all nodes of the model [3][4][5]. This approach doesn't consider the change of the bus rotation axis during the rollover process.…”

“…In addition, ECE R66 prescribes simulation model that should be able to describe the real physical behavior of the bus superstructure during the rollover [1]. Nowadays there are different modeling approaches of the body structure load conditions during the bus rollover [2][3][4][5][6]. In many of them the model loading is implemented with predetermined kinetic energy [3][4][5][6], but these approaches don't consider the bus rotation process which occurs when the bus impacts the ground (rigid surface).…”

The main objective of this study is the search for methods of verification of bus rollover finite element simulation which can replace a full-scale verification rollover test using single bus section. An overview of the main verification methods of the computer simulation results of bus rollover is provided in the article. A bus section rollover test is conducted. A comparison between calculation and experiment results is performed. Features of bus section motion, which affect the construction deformation value, are analyzed on the basis of received good convergence between calculation and test results. The mathematical model of planar motion of the bus section until impact with ditch surface is given. This model can be used to verify values of the center of gravity velocities and accelerations of the bus section, obtained as a result of an FE (finite element) simulation.

This paper deals with a rollover computer simulation (according to ECE R66 Regulation) of the bus section, which is performed on the base of a light commercial vehicle. It gives an overview of the used simulation approaches. Comparison between the calculative and experimental data is implemented on the base of one of the specified methods. It considers in details the bus rotation process, which occurs when the bus impacts with ground. The results of the analysis allow us to make a conclusion about the bus rotation influence on the bus body deformation.
