Designing and Static Analysis of the Roll Cage of an All-Terrain Vehicle (SAE e-Baja) 2020-28-0378

An All-Terrain Vehicle (ATV) as defined by the American National Standards Institute (ANSI) is a vehicle that travels on low pressure tires and with a seat that is straddled by the operator, along with the handlebars for steering control. A roll cage can be defined as a skeleton of an ATV. It forms a structural base and 3-D shell around the driver. In case of impacts and roll over incidents, the roll cage is responsible for the protection of driver. The objective is to design, analyze and optimize the roll cage under a set of particular rules given by Society of Automotive Engineers (SAE). The static analysis is carried out using CATIA V5 software for different collisions like front, side, rear and roll over. The main objective of the analysis is to obtain a roll cage enough strong to bear such adverse conditions as well as light in weight for better performance. The safety of roll cage can be ensured by obtaining optimum factor of safety.
