ABSTRACT: Chassis is an indispensable structure of an
automobile, especially in a racing car. Good designs allow a light, stiff and
extremely safe chassis to be produced at a reasonable manufacturing cost. A design
model of the chassis was prepared using CATIA according to the guidelines
provided by SAE. Many design iterations were run in order to determine the best
combination of vehicle mass, component packaging, ergonomics and weight
distribution while still ensuring driver safety without any compromise. During
the FEA tests, Stress distributions, displacements, frequency nodes were
analyzed and the results were found satisfactory. Based on the analytic
results, the chassis was optimized accordingly and then fabricated. Impact
attenuator plays a vital role in vehicle safety, when mounted on the front
bulkhead of the vehicle. The structure of the impact attenuator was designed
according to the SAE guidelines. The crash simulation of the impact attenuator
was carried out in the FEA tool and the results were found satisfactory. Thus
Impact attenuator was fabricated.
