An appropriate design of centrifugal fan is significant for satisfactory performance of the system. Centrifugal fan has wide applications in industries where the continuous air flow is required for various applications. In this work, the modal and fatigue analysis of centrifugal fan impeller with backward curved vanes are carried out using commercial software ANSYS in order to obtain the natural frequencies and mode shapes of the impeller. Further, fatigue analysis is performed using Gerber stress theory approach with the intention of estimation of the fatigue life, safety factor and damage of impeller.
