Analysis of the coach rollover scenario

Belingardi, G. / Martella, P. / Peroni, L.

A multibody model describing the behaviour of an M3 class coach in a rollover was developed. The model was validated by comparing the numerical results with the results of experimental rollover tests performed within the enhanced coach and bus occupant safety project. Through such numerical model, the approval tests, stated in the ECE66 regulation, were analyzed in depth. The simulations showed that the presence of pasenger onboard, not taken into account in the regulation, considerably affects the deformation of the structure. The calculations showed as well that influence on the deformation of the structure is strongly dependent on the passenger restraint configuration. the injury risk for passengers of coaches in a rollover accident was evaluated through the use of the mathematical model of crash test dummies. The simulations showed that the use of safety belts considerably reduce the injury risk.
