On the old board we had several threads identifying links to articles on vibration, alignment, balance. One of these old messages is attached. But it is probably out of date (old links not valid). Let's build another one.

Please post sites that you think have useful info.

Entek had some good papers from Enteract conferences. I don't know where on their site those papers have moved to. Although there is a backdoor way to access some of the papers:
http://www.google.com/search?hl=en&q=site%3Ahttp%3A%2F%...tekWebST.nsf%2Ffiles Does anyone know an easier way to access these?

CSI had some good papers. I don't know where on their site those papers have moved to. Does anyone know how to access them?

Since I have most of my technical research links at work, all I can contribute from home are these few. I have time for this board at home, but little it at work. [IT Big Bro is watching!]

Vib Analysis Articles:

http://www.plant-maintenance.com/maintenance_articles_vibration.shtml

That SKF Interactive Engineering Catalogue is a handy one. I use it often.

Here is one that is heavy on theoretical analysis of motor vibration from Timo Halopinien (who posted on the board) and his colleagues. Items available for free download are bolded. Make sure to check all the years (on the left).

Here is a great document to assist in evaluating bearing failures:

SKF Product information 401 "Bearing failures and their Causes"

It is available for free download here:

Is this the CSI stuff you were looking for Pete?

http://www.compsys.com/drknow/aplpapr.nsf?OpenDatabase&...1&Count=50&Expand=11

Yes, that's it. That CSI "Dr. Know" website is a great resource. Thanks for helping me find it again.

http://www.sea.siemens.com/motors/product/mtallpapers.html has some good information.

Those are good practical motor articles, Bill.

Here's one with a lot of theoretical rotodynamic stuff
http://www.rotordynamics.org/technical_papers.htm

Pete,

Regarding the Enteract papers, yes they are very nice collection of practical and promotional stuff.

I tried for months to find out a way reach them but unfortunately I could not after Rockwell automation purchased the company. Actually, I was really happy to see such good stuff provided freely on the web.

Before the files were blocked I downloaded (maybe in 2002) a zipped file of 27 Mb for one year (1997). I clearly remember a strange note there for purchasing the CD of the same downloadable material. I still do not know if the availability of the conferences/papers was by an intention or by a mistake.

Interesting articles on couplings, etc....

rustythevibeguy,
how get I permit joining this website?I cant see articles,
