rim is made of rectangular sheet metal and is calibrated too.
Description:
Wheel rim is that part of an automotive where it undergoes static and fatigue loads because it traverses on a lot of roads. This develops heavy stresses in the rim and thus it is necessary to determine the critical stress point and how many number cycles the rim will run. For modal analysis, the model has to be built, loads are applied and solutions are obtained. Then results have to be reviewed.
The underlying feature of all specific fatigue failure mechanisms is that there is an existence of cyclic stresses at points of the component. These cyclic stresses can give rise to damage accumulation developing a crack and finally leading to failure. The fatigue failure mechanisms are of two kinds-primary and secondary mechanisms which are elucidated in detail in the project.
Conclusion:
From the results of this project, it has been found out that steel alloy is more feasible to use and have more life and durability than Aluminum. In the future, optimization of material thickness is done to reduce material consumption. Furthermore life of the component can be improved by fatigue strain life approach.
