Abstract: The main objective of this research work is to find the mode shapeand corresponding natural frequency of a roll cage for an ATV. Finite element analysis is used to determine the mode shapes and frequencies. We have designed a roll cage which consists of both structural base and 3-D shell which protects the user in case of impact and roll over incidents. CATIA V5 has been used for modeling the roll cage and ANSYS 14.5 for FEA analysis. The body shape of the roll cage is fixed from the front end. The frame of the roll cage consists of three main parts known as boot space, driver cabin and engine chamber. The results shows that the range of frequencies varies from(0-4.883e-004)Hz.
