Summary:

For the validation of a new design of a wheel, the conventional fatigue tests may not be entirely sufficient. They may give us the success or failure, but they may not help us any further in improving the design. Experimental Stress Analysis (ESA) is becoming increasingly crucial for the validation of any new design of the wheel. One can know the exact stresses acting at a point on the wheel during its operation with the help of ESA, making it very helpful for further upgradation in design. However, requirement of a prototype makes the validation process laborious, costly and time consuming. Finite Element Method (FEM) has evolved as a resourceful tool for analyzing various components under a variety of operating conditions. It is being used not only to predict the critical points bearing the highest stress in a wheel, but also to predict its fatigue life. However, it is still not very reliable due to its deviation from the ESA observations. The present study focuses on the validation of a new design of forged aluminum alloy wheel using ESA and FEM by comparing with the existing design. The analyses using both the methods were compared and correlated using Required Fatigue Strength (RFS) calculation
