Abstract

Coach rollover is a less frequent accident characterized by a high risk of injuries for the passengers. The vehicle should absorb the impact energy by plastic deformation of the structural components it is made of. At the same time the survival space for passengers has to be preserved by avoiding the intrusion of structural components as prescribed in ECE 66 regulation. The purpose of the present study is to improve the coach design in order to guarantee the safety of belted passengers while fulfilling the requirements of the regulation. With this aim a multi-point optimization methodology has been applied on a mixed multibody and FEM model that simulates a coach module during a rollover accident. EuroSID-1 dummies have been introduced in the module for the evaluat
