Unique Fan Vibration Problems: Their Causes And Solutions
MetadataShow full item record
Operating requirements for new fans demand that greater attention be given to the design of the total installation including everything from the foundation to the ducts. Rotor dynamic analysis without adequate consideration of the structural and foundation dynamics and of the fluid dynamics and acoustics of the entire system is often not sufficient to deal with fan vibration problems. This paper discusses a multi-disciplinary approach to evaluate existing fan system designs for root causes of overall vibration problems and the development of methods to solve them. Actual case histories are presented which cover the latest field instrumentation and evaluation techniques in the analysis of fan vibration problems.
