Contexto: "This simulates the situations in which vehicle may fall over on its front side as there won’t be any direct forces that would cause rollover thus rollover impact was analyzed for 2.5 G’s of decelera tion hence taking deceleration during vehicle impact a = 2.5G. This force is applied on 2 nodes of the front Lateral Cross member (LC) so from Eq. 1, we can calculate front roll over total deformation and maximum stress as shown in Figs. 14 and 15."

Definição: "Safety restraint systems greatly reduce the potential injury risk during vehicle accidents. One major type of accident still remains without adequate occupant protection: Vehicle Rollover. Since rollover experiments are difficult to perform, rollover models can help to understand this type of accident. It will be shown, that already quite simple models reveal important properties of vehicle rollover. The influence of various parameter variations can be investigated. Based on a simplified modeling approach, it is possible to develop an analytic stability boundary, which helps to detect an imminent rollover. This is the base for future occupant protection systems."
