Abstract
Importance of wheel in the automobile is obvious. The vehicle (car) may be towed without the engine but at the same time even that is not possible with out the wheels, the wheels along the tyre has to carry the vehicle load provide cushioning effect and cope steering control. The main requirement of automobile wheel it must be strong and perform all operations above functions. It should be balanced both statically as well as dynamically. It should be lightest possible so that the unsprung weight is least. The wheel has to pass three types of test before going production, they are cornering fatigue test. Radial fatigue test and Impact test. In this thesis radial fatigue analysis is done to find the number of cycles at which the wheel is going to fail. The wheel is meshed using SOLID 45 element. A load of 2500N was applied on the hub area of the wheel and a pressure of 0.207N/mm2 is applied on the surface of rim.
