The document describes a study on the design and analysis of an automobile wheel rim using different fillet radii and Y-spoke angles. A 3D model of an 8-spoke alloy wheel rim was created in CATIA and imported into ANSYS for structural analysis. The wheel rim was analyzed under a 1000N remote force and 245kPa internal pressure with varying fillet radii from 0 to 5mm and Y-spoke angles from 35 to 55 degrees. The results showed the total deformation was highest without a fillet and lowest with a 5mm fillet. For the Y-spoke angle variation, the total deformation was lowest at 55 degrees. Increasing the fillet radius and optimizing the Y-spoke
