Can somebody suggest me a book deals exclusively about fan vibrations and its solutions.Thanks.

There is a book titled "Vibration of Bladed Disc Assemblies: D.J. Ewins and A.V. Srinivasan, eds. ASME, New York, NY 1983, 160 pages" that probably is out of print and also is highly theoretical, something I suspect you don't need at this stage.

I would suggest you do a google search on fan vibration and see what you might be able to extract. There appears to be some worthwhile materials out there.

Gevenag,

I have not seen a book completely devoted to the topic of fan vibrations. Here is a book that claims some discussion about vibrations:

I have worked on many types and sizes of fans (up to 8000-hp) to solve sound and vibration problems. I have had to acquire my knowledge from a lot of sources, but I have not seen a book that puts everything you need into one convenient place. Here are a list of topics:

Fan types and applications
Fan operating principles (the fan curve and scaling laws)
Fan control methods (variable speed, cariable blade angle, inlet/outlet dampers, and inlet vane)
Sound and vibrations unique to fans (vane-pass, surge/stall, turbulence)
Vibration measurements including torsional
Rotor dynamics
Structural dynamics including testing methods
Bearings including lubriucation and cooling
Foundation types and design
Rotor balancing methods
Shaft alignment
Sound measurements
Noise control methods

I would write a fan vibration book if I could make some money by selling it!
