In today's scenario, most of the Automobile Industries focus is on strength enhancement of automobile parts & reduction in the weight of the body parts of the vehicle. Normally Fender is used to avoid mud, sand, liquids and rocks and other road sprays from rotating tire that are thrown into the air. Fenders of heavy automobiles are manufactured from sheet metal which is having thickness less than 6 mm & are often subjected to vibratory loads which leads to Structural Failures. The 3D model of

In Modal Analysis various mode shapes indicating minimum to maximum deformation with images were obtained and also Natural frequencies were known, In Harmonic Analysis it was seen whether the plane sheet fender or sheet with parallel ribs or sheet with cross ribs performs better. The experimental Fast Fourier Transform was carried out. Comparative analysis was carried out between Analysis results and experimental results for frequencies. FEA of Original Fender and Original Fender with Parallel vertical ribs was carried out. In result, output acceleration for sheet with vertical parallel ribs was found to be optimized.
