DESIGN AND STRUCTURAL ANALYSIS OF BAJA FRAME WITH CONVENTIONAL ANDCOMPOSITE MATERIALS

Abstract

Abstract: Anall-terrain vehicle (ATV), also known as a quad, quad bike, three-wheeler, orfour-wheeler, is defined by the American National Standards Institute (ANSI) asa vehicle that travels on low pressure tires, with a seat that is straddled bythe operator, along with handlebars for steering control. An ATV that abides bycertain rule sets that are devised by the SAE for a competition is known as BAJAS.BAJA SAE is an intercollegiate competition organized by Society of AutomotiveEngineers (SAE) to design, build and race off-road vehicles. Chassis is animportant part of the BAJA vehicle that supports body and other different partsof the vehicle. It also surrounds and protects the occupant in case of impactand roll over incidents and also gives the aesthetics of the vehicle. Thesevehicles are designed to run and perform on any surface irrespective of theground conditions. The design structure of an ATV solely depends upon itroll-cage. As an ATV is an experimental vehicle the design procedure of itsroll-cage plays a critical role to give maximum possible strength while keepingthe weight minimum. Roll cage of an ATV also absorbs various impacts during anevent or in test runs. The aim of the project is design of Roll cage using theCATIA software and analysis is using the ANSYS software. We select two types ofanalysis in this project one is the static load condition and another one isthe modal analysis for calculating natural frequencies of different modes,finally finding out the stresses, strains, and deformations in different casessuch as front impact, side impact, rear impact by using the different materials(AISI 1018, AISI 4130, EGLASS EPOXY, CARBON FIBER) and finally concluding the material which is optimum for the Roll cagebased on the values.
