Solid Modeling ability provides state of the art design capabilities for faster, more accurate, depictions of fan designs. This allows for a detailed review and analysis of fan assemblies and parts prior to actual fabrication. Models generated using 3-D elements can be linked to Finite Element Analysis packages to perform various engineering tasks.

Finite Element Analysis programs are used for impeller stress level evaluation, fatigue analysis, and modal/vibration prediction. FEA analysis studies allow for the selection of optimum material types, gages, joining methods, and construction features. Strain gage testing is used to back up stress level calculations.

A vacuum test chamber is used for verification of wheel failure predictions. FEA modal analysis permits the engineer to view the vibrational mode shapes, and readily solve potential problems. Modal predictions are verified with FFT (Fast Fourier Transform) analyzer and impact hammer.
