I'm presently working in the area of SHM of Bolted joints. The components used are NI Multifunction DAQ USB-6363, Piezo - PZT-5H.
Using LabVIEW, generated Gaussian pulse (10V, 100kHz) to actuate PZT1. The output signal from DAQ was measured with DSO (Amplitude-0.004, Frequency:20 Hz) to actuate PZT1.
I'm unable to get the signals from the sensors (PZT2) as a response after the wave passed through the bolted surface. I have attached the front panel and block diagram of Gauss signal PZT1 (generation) waveform and PZT2 sensing (acquired) waveform.
