Different type of materials and foam application on vehicle rollover analysis of buses

A roll-over event is one of the most crucial hazards for the safety of passengers and the crew riding in a vehicle. In the past years it was observed after the accidents that the deforming body structure seriously threatens the lives of the passengers and the rollover strength has become an important issue for vehicle manufacturers. Today the European regulation ?ECE R66? is in force to prevent catastrophic consequences of such roll-over accidents thereby ensuring the safety of vehicle passengers. In this study effects of using different type of materials and foam application on vehicle rollover analysis were investigated. As a result of this study it is seen that using materials which has better mechanical properties and application of foam to the steel sections increases the vehicle safety during rollover crashes.
