Harmonic Analysis

(OP)
Hello Friends,

I would need ur help in inputting vibration test schedule data for my harmonic analysis. I have a fuel rail, I found the resonating frequencies. I have my vibration test data given as follows for parallel to bore(vertical)
Frequency(HZ)  Accelaration(g)
20                3.3
500               3.3
800               7.1
950               4.1
1160              5.6
1375              6.5
1720              3.9
2000              3.9

Could someone help me how to go abt with my harmonic analysis, the rail is like a thin circular tube with 2 brackets.Appreciate ur time n help.

Thank u all

cheers

RE: Harmonic Analysis

You use the spectrum response method by inputting the frequency-v-acceleration as your curve. Combine your results using SRSS, Sum of Root Sum Squared.
