Industrial Centrifugal Fan Manufacturer Halifax Fan Ltd Employs Fine Element Analysis for Long Term Reliability, Greater Efficiency and Competitive Costs

Brighouse, United Kingdom (PressExposure) September 24, 2009 -- The Finite Element Method, more commonly known today as FEA, was originally developed in the 1940s by pioneers such as Richard Courant and is a mathematical tool for examining the elasticity and strength of complex structures by mathematically breaking the structure or domain down into a mesh of discrete sub-domains or elements.

However, only with the evolution of the computer, has FEA today become a cost-effective tool for studying fabrication designs in great detail. Halifax Fan’s FEA software interfaces with their CAD system and simplifies anad speeds the creation of the mesh structure to be analysed. FEA greatly improves the application of stress analysis and, using graphical methods, quickly and clearly, shows on the computer screen, areas of high stress to pinpoint where a different or thicker material might be needed to meet the specified operating conditions.

Finite Element Analysis (FEA) enables Halifax’s fan designers to assess not only the rotating elements of the fans but also the stresses on high pressure and explosion-proof fan20casings and the motor and bearing pedestals. Vibration analysis and the identification of natural resonant frequencies can also be analysed and thus catered for the most common use of FEA at Halifax Fan is to examine the stresses on fan impellers, especially for more critical models such as high speed fans and those subject to high cyclic stress and temperatures.

In the case of high pressure and explosion-proof fans, FEA also facilitates a detailed stress analysis of the fan casings and their explosion containment capabilities. Case deflection studies ensure that when working with mechanical seals there is minimal case movement ensuring pressure integrity.

Recently, where high efficiency, variable speed operation is required, FEA has been invaluable for calculating the natural frequencies of the bearings and motor pedestals to help with the avoidance of potentially damaging mechanical resonance FEA can also be used to examine the natural frequency on the bearing and motor pedestal.
