Abstract
The finite element modeling and analysis have been performed to investigate the effects of nitriding, cold rolled and shot peening on fatigue life of an automotive lower suspension arm component which fabricated of SAE1045 steel. The finite element analysis (FEA) results indicate a great effect for all surface finish parameters on fatigue life. It shows that nitriding increased the fatigue life of the component better than shot peening, while cold rolled effect was between them. In a nut shell, nitriding can be considered as the best surface treatment to improve the fatigue life of the automotive lower suspension arm which fabricated of SAE1045 steel.
