Design and Analysis of Independent Suspension System for an All-Terrain Vehicle

mechanical enngineering

An All Terrain Vehicle (ATV), as the name defines is a vehicle designed to handle a more variety of terrain than most other vehicles. Over the period ATVs have been used for performing number of applications ranging from military to desert, jungle safaris, hilly areas. 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. The study in this paper is carried out on the topic design and analysis of independent suspension system for an all-terrain vehicle(Double wishbone A-Arms and H-Arms). The purpose of this study is to design an independent type suspension system which can rely on any type of off-roading conditions. The focus of the study is to provide comfort to driver by reducing the effects of bumps and also improving the dynamic parameters of the vehicle. Suspension system is an important part of any vehicle, as it helps in resisting the unwanted forces so that driver feel comfortable while driving. An independent suspension allows wheels to rise and fall on their own without affecting the opposite assembly 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.
