FRF impact hammer analysis with repeat measurements (PCB)
Framework sequence with optional setup and a series test in an endless loop.
The PCB hardware variant of the FRF impact hammer analysis with an identical test sequence: setup mode, series test with three averaged impacts, FRF evaluation with peak detection and loss factor. In addition this configuration contains a calibration sequence for the measurement microphone that checks RMS level and frequency position at 1 kHz against a calibrator, plus an extensive product list with more than 50 entries in several categories as an example of product management.
Workflows in detail
-
Main
Framework sequence with optional setup and a series test in an endless loop.
Start → if "setup": call Setup → endless loop (start query → call Measure → store) → end.
-
01 Measure FRF 3x
Triple FRF measurement with averaging and decay time.
Start → loop "FRF averaging" (excite → signal trigger force sensor → force sensor measurement → microphone measurement → FRF analysis → decay time) → end.
-
90 Calibration MIC1
Microphone calibration against a 1 kHz reference.
Start → trigger → MIC1 measurement → analysis (RMS values → FFT → frequency position at 1 kHz) → store → end.
