This paper gives the overview of the computer simulation methods of the bus rollover conditions. The rollover computer simulation of the bus section, which is performed on the base of a light commercial vehicle, is implemented according to the ECE R66 Regulation annex 9 requirement. The plastic hardening curve of the steel, obtained from the test, is used in the simulation model. The rollover test of the bus section is conducted considering requirements of the annex 6 of this Regulation. The comparison between the calculative and simulation data is carried out on the basis of the residual deformations values. The bus rotation process before its impact with ground is considered in detail at the computer simulation. Also the change of the kinetic energy during the rollover is analyzed. The results of the analysis allow us to make a conclusion about the bus rotation influence on the bus body deformation.
