During every start-up and shutdown of centrifugal fan, the fan blades are subjected to centrifugal, bending and vibratory loads. This repeated start-up and shutdown can reduce the life of fan blades. A fatigue and modal analysis of the fan is, therefore, very important in the design and development of fans, to prevent premature failure. In this paper the finite element analysis of a centrifugal fan impeller, for a high tuned design is carried out using ANSYS. The Finite Element Analysis is to be done on the following platform, “Fatigue and modal analysis...
