Design and Analysis of Al 356.2 and ZK60A Wheel Rim with Radial and Spiral Flexures

Abstract

—In the present state of affairs, light weight wheel rim plays a surpassing role in automobile which has to
withstand high stress. The stress on the wheel rim may be subjected to bending and torsional loadings. Improvement in
design of rim emphasis high stress withstanding capacity, long life, steering control andthere by reduces the weight of
the rim and unsprung weight of the vehicle which again assists in less consumption of fuel. Wheels may be made of cast
aluminium alloy or Mg alloy are widespread to their aesthetics and lighter weight compared to steel wheel rims. In this
project work, a parametric model of wheel rim of Al 356.2 and ZK60A alloys were designed with radial and spiral
flexures using CREO. Design is analysed using ANSYS software on bending and radial endurance tests as key aspects in
accordance with the specifications prescribed in the industrial standards. From the results, it is found that factor of
safety for Al 356.2 and ZK60A with spiral flexure is greater than radial flexure.
