DESIGNING THE REAR UPRIGHT OF AN ALLTERRAIN VEHICLE (ATV) THROUGH A PROCESS METHODOLOGY

The benefits of even slightest of weight reduction on an ATV are numerous. It directly affects the fuel efficiency and overall performance of the vehicle. Therefore, weight reduction becomes crucial in the realm of modern ATV design. Rear upright is one of the most stress sustaining and critical component of All Terrain Vehicle (ATV). This paper attempts to provide a process methodology to design rear upright for Allterrain vehicle. This methodology is used for designing and optimizing a rear upright capable of withstanding 3 standardized tests i.e. 2m Drop, Front Impact and Side impact Test. For designing, a 3D CAD model is created by using SOLIDWORKS. Finite Element Analysis (FEA) Static as well as product life analysis are carried out in ANSYS to understand its behavior under operating conditions. The target is weight reduction without compromising on the structural strength i.e. an optimum minimum factor of safety (FOS). The designing process also keeps a check on design feasibility
