ROLL-CAGE FRAME DESIGN FOR AN ALL-TERRAIN VEHICLE

Abstract

All terrain vehicles (ATV) are designed to run and perform on any surface irrespective of the ground
conditions. The design structure of an ATV solely depends upon it roll-cage. As an ATV is an experimental vehicle the
design procedure of its roll-cage plays a critical role to give maximum possible strength while keeping the weight
minimum. Roll cage of an ATV also absorbs various impacts during an event or in test runs. To verify the design finite
element analysis can be done for static loads with defined impact times and modal analysis for calculating natural
frequencies of different modes. This paper will cover design analysis and procedure of roll-cage frame to ensure the
vehicles safety in all possible conditions.
