I have measured data of a vibration with chirp input were I suspect unwanted shock events occurred. I therefore thought about computing the spectrogram of my time histories to check the frequency content.
I am however not fully sure about what to look for. My idea would be to look for a straight line at a given step in time across all frequencies (because a shock event, like two bodies hitting each other, is normally short in time and excites all frequencies). Is that correct?
Are there other ways to detect shock occurrence?
