摘 要: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.
