Dear all,
I have to measure the natural frequency of a rotating shaft by using an PCB 352C33 ceramic accelerometer. It has a calibration coefficient of 100mV/g. In order to do this I should hit the shaft at least 3 times with a PCB 086C03 impact hammer (with calibration of 2.25mV/N), and record the data of the hammer and the accelerometer at 5kHz. They are connected to the C connector on a myRIO. After doing the experiment, I should determine the Frequency response function.
I have never done this type of analysis, so I am asking for tips. I started by calculation the force from the voltage output of the hammer, but as for the FRF I don't know where to start from.
Any tips or similar LabVIEW examples?
Thanks in advance
Frenka :))
