Abstract

Vehicle accidents are of major cause to lead severe injuries and probability of occurrence of death when injury rate is severe. A rollover is a type of vehicle accident in which a vehicle tips over onto its side or roof due to the high centre of gravity and working on slopes and uneven terrain. The most common cause of a rollover is loss of balance when speed of the vehicle is too fast. All vehicles are susceptible to rollovers to various extents. After a rollover, the vehicle may lie on its side or roof, and block the doors complicating the escape for the passengers. Earthmovers are equipped with protective structure which even under rollover, provide safe zone (no intrusion by the structure) for operators. Such Rollover Protective Structures (ROPS) are expected to meet minimum performance criteria to ensure occupant safety. ROPS is likely to collapse towards the occupants and cause severe head injuries as the space left for survival reduces drastically. This Paper depicts the importance of the Finite Element Analysis performed on newly designed SD190 FULL ROPS as per ISO 3471. It also handles the Optimization study performed on few of the load carrying parts in the Structure.
