September 2010





























Equipment:

• 4 accelerometers ICP 100mV/g
• Signal conditioning NI-SCXI

Testing conditions

• Free vibration (hammer test)
• Free vibration (pull & release test)
• Forced vibration (motor unballance excitation)

  Pull & release test


  Weak link for pull & release test



Data processing

• Spectral analysis
• Operation modal analysis
• Wavelet analysis
