the purpose of designing of this four wheeled all terrine vehicle for the transportation in hilly areas, farming fields and. It is designed for off-road uses and for endurance of rough hilly areas. The skeleton of the off road vehicle is called roll cage. The total load of the vehicle acting over the roll cage only. The design fully depends upon the material selection, frame design, cross section determination, and strength & analysis report. We studied all the parts of the roll cage to analyse the efficiency. We used high end software's like solid works & action for roll cage designing purpose & ANSYS for analysis. We made different type of designs of an ATV & analyse the deformations occurred.
