IRJET - Design and Analysis of BAJA Rollcage

This document describes the design and finite element analysis of a roll cage for an all-terrain vehicle (ATV). The roll cage is designed to withstand forces from various impact directions. AISI 4130 steel is selected for its strength, durability, and weldability. The roll cage geometry is modeled in CAD software and analyzed in ANSYS for front, rear, side impacts and rollover. Front impact analysis at 7G deceleration showed a maximum von Mises stress of 623 MPa and a safety factor of 1.04, indicating the design is safe. Similar analyses were performed for rear and side impacts.
