Static Structural Analysis of Roll Cage of an All-Terrain Vehicle

Abstract

The objective of this research is to analyze roll cage of single-seated off-road all-terrain vehicle which can sustain rough terrain in all types of weather without damage. The capability of these vehicles includes acceleration, maneuverability, rock-crawl and hill climbing on surfaces. A roll cage is considered as a framework of an all-terrain vehicle (ATV). It forms a three-dimensional structure around the driver. It consists of steel members. The roll cage of vehicle plays crucial role in safety of the driver. It contains driver, engine, brake system, steering mechanism. Roll cage must have suitable strength in order to protect the driver in event of rollover or impact. Roll cage safety features were first implemented in accordance with the 2019 Baja SAE Competition Rules [1], which served as a baseline for roll cage design. Design of roll cage is done in CATIA V5R20, and static structural analysis of roll cage is done using ANSYS Workbench 16 for various collisions like front, rear, side, roll over and vibration analysis. To obtain required factor of safety (FOS) in all the loading conditions is the main objective of analysis of design.
