Design and Analysis of Eco Car Chassis with Different Profiles

Abstract

Formula Student Racing competitions are held at various Formula SAE circuits globally. Chassis serves as an important component in the race car design. Thus a solicitous analysis is expected out of the formula car. It is also noted that the weight of the car is inversely proportional to the performance of the car hence need for optimization. A high speed protection system plays a major role in the race car design such as front impact, rear impact, side impact and roll over analysis. Also, there exists a problem of the torsional rigidity as far the dynamics is considered. This paper aims at the design aspects and the analysis insights of the race car. The car is modelled according to the 95th percentile male that can fit inside the cockpit of the chassis. As the car travel at the high speed, the protection has been designed to the car in such a way that stresses are minimum and the performance is maximum. Finite element methods are used for the analysis and the design of experiments is created for the optimization of the chassis. To avoid any possibilities of failure of the structure and thus to provide enough supporting member to make the region stronger in term of deformation . Finite element analysis enables to predict the region that tends to fail due to loading, the distribution of stress and strain on the chassis, both component as well as the material costing. The main objective is to study the effect of the validations of the FEM result are given using the different profiles like RECTANGLE, CIRCULAR, AND I SHAPE convergence methods for car body and the equipment.
