Replacing materials design & analysis of automobile chassis

Abstract

The automotive chassis serves as a frame work for supporting the body and different parts of the automobile. Also, it has to withstand the shock, twist, vibration and other stresses caused due to sudden breaking, acceleration, shocking road condition, centrifugal force while cornering and forces induced by its components. The chassis acts as the backbone of a heavy vehicle which carries the maximum load for all designed operating conditions. This paper describes design and analysis of heavy vehicle chassis as the prime objective of any automobile industries in today’s fast changing world. In the present paper the pertinent information of an existing heavy vehicle chassis replacing materials of high specific weight with lower density materials without reducing rigidity and durability. Replacement of steel with aluminium, magnesium, composites are taken for modelling. Designing using computer aided design software catia and analysis by subjected to the identical load as that of a chassis. The numerical results are validated with analytical calculation considering the stress distribution and deformation using the ansys software.
