ECE R66 regulation provides realization of the passive safety calculative estimation with using the computer simulation tools. Therefore the actual task is the body safety estimation calculative methods introduction to the using in the design departments. In this paper rollover computer simulation of the bus which is based on the chassis of the light commercial vehicle was performed using the constructed finite element model. Its crash loading was implemented by rotational rigid wall. Application of this method is explained that unlike under the gravity rollover, it doesn’t require passenger mass distribution over the model nodes. The task calculation takes significantly less time in this formulation. The results of the study can be useful for specialists working in the field of the bus passive safety calculative estimation.
