It was found that as per Fatality Analysis Reporting System (FARS) rollover events cover more than 30% of the crashes. A large number of road accidents take place every year causing many fatalities and severe injuries to the vehicle occupants. Over 9 thousand people are killed yearly in rollover crashes. In 2001, 10.5% of all fatal crashes were rollovers, though only 2.2% of all crashes were rollovers. Almost fifty percent of fatalities occurring in Sport Utility Vehicles (SUVs), pickup trucks, and minivans are due to rollovers. This makes rollover a serious threat for all vehicles, but especially larger utility vehicles (NHTSA, 2002). Figure 1.1 graphically illustrates the dangers of rollover accidents. If sufficient attention is given to injury impediment, by building the vehicles innately safer, this problem can be reduced. Among the various modes of vehicle crashes, rollover crashes are often very severe and threatening to vehicle occupants. The rollover crash accident of vehicles, although occurs less frequently than any other type of accident, the fatality rate and severe injuries are highest in rollover crash. Hence the structure of the vehicle needs to be strong enough to ensure the minimum damage and at the same time it should absorb maximum impact energy. In this work numerical simulation of pick-up rollover test using finite element method is followed. As shown in figure 2, during rollover vehicle roof, A Pillar and B Pillar play an imperative role to avoid vehicle collapse. Using Finite element Approach optimizes design of roof and its surrounding systems will be finalized to reduce vehicle collapse during rollover accidents .We have also studied the use of different materials for the top in order to decrease the thickness of sheet metal of top segment while also behaving safe in the regulation. The technique is being carried with the aid of Finite Element Analysis (FEA) and Computer Aided Engineering (CAE) routines to upgrade a roof material.
