What to expect

Vibrations can indicate damage to machines. But what are vibrations physically and how can they be measured? Based on the answers of these questions, this webinar will present various evaluation methods over the time domain, including the calculation of digital filters, levels and limit curves, the frequency domain and the order domain. On the subject of order analysis, we will also show how resonance frequencies, speed-dependent vibrations or bending and torsional vibrations can be evaluated using measurement technology.

Agenda: 

  • What are vibrations? What sensors are needed? Acceleration vs. velocity vs. displacement
  • Time domain analysis:
    How to calculate digital filters, levels and limit curves e.g. ISO 10816/20816?
  • Frequency domain analysis:
    What is the FFT fourier transform?
  • Analysis in the order domain: resampling, order analysis, orbit representation
  • What are resonant frequencies, speed-dependent oscillations, bending and torsional oscillations?
