Background. The problem of reducing severity of road traffic accidents (RTA) is always relevant.Particular attention is paid to improving the passive safety of buses, as accidents involving passenger vehicles are characterized by severe injuries and wounds, obtained by the passengers in an accident. It is well known that one of the most dangerous types of rollover accidents is characterized by high dynamic loads acting on the bus body constriction. The safety requirements for passenger carrying systems of large vehicles are regulated by ECE Regulation number 66, involving the assessment of passive safety as by the results of the calculations and also by the results of computer simulations. Usually full-scale bus rollover simulating tests require high material costs. In this regard, currently the computational methods implementing a reliable virtual simulation of the emergency conditions of body structures loading play a significant role in the assessment of passive safety. However, special consideration should be given to the adequacy of the study design model when using computational techniques. The main purpose of the study is to confirm the legitimacy of the practical application of the computer simulation results on conditions of separate sections and bus body rollover with the use of their detailed finite element models to assess the passive safety of buses.
