Still the question about the rms.
If I did one trial and collected 100000 data (acceleration-time), can I break these data into 100 set (100 data/set) and calculate rms for each set. I get 100 data and they're all rms data. Then I do the FFT for these 100 rms data. Can I say it's the...
My laser measurement system is a laser transmitter or tracker. Will sit on either the floor or roof truss.
My question now:
I have the data for Acceleration-Time from the accelermometer. How can get the RMS acceleration/Frequency plot? It might be 1/3 octave frequecy. Any suggestions?
Thanks.
I have found some good papers from: http://cganda.com/
My new questions:
1. I used accelerometers to get the vibration data and I get the acceleration signals. How can get the velocity signals?
2. How can I get the root-mean-square (rms) values for the FFT analysis? What's the benefit of rms...
Yes, these buildings are all close to a busy highway.
My questions is not only focusing on the choosing the better one, but also to find out and set up some criteria for the vibration evaluation for our future product and project. We're trying to learning. Thanks and please input any suggestions.
Thanks Tmoose!
I think the X units on FFTs is Hz to Y Amplitude(unit mm?). It's just a data plot after the FFT.
As for the magazine paper, do you have more details, such as title...
Sorry for the last post.
Here are links for 3 FFT plots:

Hi all,
I don't have much background in vibration analysis.
We're looking for a new building for our laser measurement system lab. We used a few Kistler 8393B2 (0-250hz response) to collect the vibration data for these new buildings and did some fft analysis. We want set up some criteria to...
