I am trying to do some impact testing to find natural frequencies. I am completely new to impact testing and labview but am trying to learn as I go. I was hoping to use the 'Impact Test' Example VI that comes with Labview's sound and vibration package to do the testing but I cannot get it to work. I am using the following setup:
- Labview 2021 with sound and vibration tool kit
- c-DAQ 9174
- NI-9232
- B&K impact hammer type 8204
- B&K accelerometer type 4517
No matter what I try the program will not give a frequency response. The problem seems to be that it does not record the response of the accelerometer. It clearly picks up the signal as it shows up in the live response panel (shown in screenshot) but nothing is shown in the frequency response, Nyquist plot or all data panels. The saved waveform files also only contain the hammer impact data.
I have tried changing the settings for the hammer and accel, changing the values in the node table, changing the window settings and turning it off entirely.
I don't know if this is a simple error in the settings on my part or if the VI is just broken. Any advice would be greatly appreciated.
