An All Terrain Vehicle (ATV), as the name implies is a vehicle designed to handle a wider variety of terrain than most other vehicles. Over the period ATVs have been used for performing number of applications ranging from military to desert and jungle safaris. The efficacy of an ATV is determined on the basis of its ability to sustain the irregularities of the terrain with ease. The system that implements the vital role of damping such undesired commotion and vibrations is the suspension system. The suspension systems are mainly classified as dependent suspensions and independent suspensions. A dependent suspension normally has a beam or live axle that holds wheels parallel to each other and perpendicular to the axle. When the camber of one wheel changes, the camber of the opposite wheel changes in the same way. An independent suspension allows wheels to rise and fall on their own without affecting the opposite wheel. The front suspension and rear suspension of a vehicle can be different as per the application requirements. The paper focuses on the designing, analysis and simulation of an ATV suspension system which was designed for a national level event namely BAJA SAEINDIA.
