Simulation-based determination of loads acting on an overturning double-decker bus

The paper presents simulation studies of an overturning double-decker bus. A simulation model of the vehicle was built using the multi-body system method in the MSC.ADAMS software. Subsequently, simulation tests of the bus rollover were conducted in accordance with ECE Regulation 66, as well as tests of a bus rollover while moving along a road curve. A comparison of the applied models and the results of the performed simulations allowed for highlighting the differences between the trajectory of the bus body falling according to the homologation test and the trajectory of the vehicle body moving under real-world conditions.
