Abstract

The wheel rim plays a vital role for good running of the vehicle and the most important safety components from a structural point of view. It must be made with adequate strength and lighter in weight to reduce the unsprung mass of the vehicle and plays a major role in vehicle dynamics. The present study deals with the comparison of structural analysis of aluminium bronze alloy wheel rim with three different compositions to enhance corrosion and fatigue resistance. The design of the wheel rim was created by CATIA V5 and structural behaviour was analysed by ANSYS workbench. The results showed that combination of 90% Al alloy and 10% CuSn) gives adequate strength compared to other combinations of aluminium and bronze. The fabrication of the rim was done by casting methods. Various test like impact, shear, hardness and ultimate tensile tests were conducted to know the mechanical strength of the rim. Salt spray corrosion test was carried out to know the corrosion behaviour of the rim and the results show that no corrosion was found up-to 240 hours
