Stress Analysis of Axial Flow Fan Impeller

摘要

In this work, stresses and natural frequencies of axial flow fan are evaluated. Various combinations of hub thickness and ring thickness are considered to calculate stresses and frequencies. It is observed that in case of solid hub the maximum stresses are induced at root of the blade and if the thickness of the hub reduces the stresses at the root of the blade increases and natural frequency decreases. Finite element analysis is done on impeller for investigation of stresses and natural frequency
