Title: Redesign of a fan support structure using Modal Analysis and FEA

Subtitle: A case study in the application of modal analysis and FEA in solving resonance problems through redesign

Date added: 08/04/2004

FEA results

Abstract: The use of model testing techniques and FEA together to solve vibration problems is a powerful technique. In the case presented, the deck structure of an I. D. fan was redesigned in order to avoid an unacceptable resonant condition. An FEA model was validated using an ODS. It was then employed to test various design configurations. A design was selected that the FEA model predicted would succeed and that was feasible from both cost and implementation perspectives. (read more)
