FAN FEAMay 5, 2010
We ran a finite element analysis (FEA) on the heavy-duty fan. We gave the fan a centrifugal load of 3600 RPM and constrained the bore. As expected, the highest stresses are found along the blade edges where the blade/hub fillet meets the blade. As you can see in the image below, the lowest safety factor remained around 10.0.
