Free Vibration Analysis Reference Center
Free Vibration Analysis Reference Center
(OP)
http://www.dliengineering.com/section.asp?nID=19
I wanted to let everyone know that we have just posted a free Vibration Reference Center on our web site. (url above)
The Reference Center contains a large glossary of vibration terms and definitions (incase you forgot what "hysteresis" or "cepstrum" means).
It also contains a ton of information on vibration analysis, machine fault diagnosis, fault patterns etc. These are presented in a logical order and are linked to a live index.
I hope you all enjoy this resource and find it useful. If you have any feedback, please feel free to email me at the address below. Also feel free to share this url with anyone who might find it useful.
As always, we we aim to educate and participate in our community as do many of you who use this forum. We hope this resource serves this purpose and compliments the numerous technical articles we also offer for free on our site.
The entire center is also available in text book format.
Enjoy!

I used the link but there was nothing there. It came up Vibration Reference Center, but unless I'm missing something, That was as far as I could go.

I didn't see anything free at the 2nd one other than the glossary.
I will mention on the firstone it looks like most of the data is intact. But I did find a hole. Click on machinery diagnoses - mechanical looseness - rotating looseness gives me nothing. Maybe it is a placeholder intended to be filled in later.
Thanks for both links. I have a good link to list of good vib article sites on reliability-magazine.com thread but I can't find it right now.

Sorry if we inconvenienced anyone. We had some technical problems with the vibration resource center. It is up and running again and we will continue to expand and improve it. Enjoy!

I did have a comment on one part on induction motors:
"Because the induction motor works by magnetic repulsion rather than attraction like the synchronous motor, it has been called a "repulsion induction" motor..... As soon as any load is applied to the motor the speed is reduced, causing the rotor bars to cut the magnetic lines of force of the stator field, and creating the repulsion force in the rotor."
I have a hard time with that. I never heard it before and I don't believe it.
"The induced magnetic field in the rotor migrates around in the opposite direction of the rotation"
That is flat-out wrong. The rotor, rotor field, and stator field all rotate in the same direction.

I forwarded your comment on to the author and will let you know when i get a reply...thanks for the feedback!
