Finite Element Stress Analysis:
Finite Element Stress Analysis (FEA) is used to accurately determine stress levels in critical components.

Backward Inclined Bladed Fan Wheel

FEA is performed on fan wheels to ensure maximum stress levels are kept below the material yield strength. The example on the right shows stress contours for a typical fan wheel.
FEA analysis is also performed to accurately determine bearing support stiffness to allow forced response vibration calculations.

Another application for FEA is to predict natural frequency for rotating assemblies. This is to ensure that the natural frequencies of the rotating assembly do not coincide with running speed, harmonics of running speed or blade pass frequency.
