Talk:Modal analysis

Untitled

"Modal Analysis, or more accurately Experimental Modal Analysis, is the field of measuring and analysing the dynamic response of structures and or fluids when excited by an input." Ummm wrong... modal analysis is more general than that. Experimental Modal Analysis should have its own entry once Modal Analysis has been written. I don't have time to propose anything right now, but I will do eventually if no-one else does. --Muchado (talk) 09:34, 27 September 2008 (UTC)

Agreed, this article is about experimental modal analysis while the more general modal analysis is based on the expansion theorem (which says you can compute the response by superpositing the natural modes of said system). Experimental modal analysis is very important and probably one of the more exciting aspects of modal analysis, but modal analysis itself is more general than just experimenting. — Preceding unsigned comment added by 134.157.34.211 (talk) 07:58, 5 May 2017 (UTC)

"Typical excitation signals can be classed as impulse, broadband, swept sine, chirp, and possibly others. Each has its own advantages and disadvantages."I would like to see an expansion on this. Would a list of advantages and disadvantages of each type of each excitation signal be suitable in a Wikipedia article? If not, I will gladly provide a place for such a list to be stored which can be referenced by a footnote. David 11:59, 2 October 2008 (UTC)

I suspect it'll be pinged as WP:OR, on the other hand Ewins or B&K almost certainly discuss it somewhere. I don't have Ewins any more, if you have please check.. Otherwise write something suitable and if it gets challenged then we'll find refs. This article isn't exactly a hotbed of activity! Greg Locock (talk) 22:24, 2 October 2008 (UTC)

2 definitions?

The lead contains 2 separate but somewhat overlapping definitions and lists of examples (first paragraph, and start of second paragraph). Would it be possible to merge these basic definitions without loosing some nuances? GermanJoe (talk) 14:43, 7 September 2018 (UTC)

Citation Needed in Structures Section

For the [citation needed] in the Structures section, regarding how the natural frequencies of a building being equivalent to the frequency of ground motions can lead to resonance, could easily be verified with A.K. Chopra’s Dynamics of Structures. Probably somewhere in Chapter 6 or 7, maybe Chapter 4. I will have to look myself and hopefully remember to come back and add this reference. — Preceding unsigned comment added by Crswong888 (talk • contribs) 08:15, 27 March 2020 (UTC)
