Diagnostic objects

The VES004 software configuration wizard comes preloaded with the most common vibration diagnostic objects to make initial set up easy for the novice.  It is also flexible, however, for the more advanced user.

Preformatted configuration tools

The image below is a screen shot of the software wizard. It shows the preformatted configuration tools.

Unbalance

Monitoring 1x rotation speed is a key indicator for rotating equipment.  Issues such as unbalance and misalignment are detected at the rotational frequency.

Machine use examples include:

  • Motor rotor imbalance
  • Spindle rotation issues
  • Flywheel imbalance
  • Driveshaft imbalance

a-RMS (Frequency domain)

Widely used for acceleration monitor of friction, a-RMS is ideal for detecting mechanical rubbing issues.  When used in the frequency domain, the specific frequency range can be targeting with either a broad or a narrow operating band.

Machine use examples include:

  • Worn tool monitoring
  • Dry sleeve bearings
  • Generic bearing failure monitoring

v-RMS (Frequency domain)

Widely used for velocity monitor of fatigue, v-RMS is ideal for evaluating mechanical stress such as bending.  When used in the frequency domain, the specific frequency range can be targeting with either a broad or a narrow operating band.

Machine use examples include:

  • General machine fault conditions

d-RMS (Frequency domain)

Traditional measurement of displacement.  It is often used for evaluating force at lower frequencies.

Machine use examples include:

  • Structural issues

a-RMS (Time domain)

Real-time broad band average acceleration indicating the amount of mechanical energy loss.

Machine use examples include:

  • Machine shutdown for process overload
  • Machine shutdown for excessive operating force

v-RMS (Time domain)

Real-time broad band average velocity indicating the rate of mechanical energy loss.

Machine use examples include:

  • Machine shutdown for general machine fault conditions

a-Peak (Time domain)

Real-time broad band indicator of impacts and transient events.

Machine use examples include:

  • Machine shutdown for impacts
  • Machine shutdown for crashes
  • Machine shutdown for pump cavitation
  • Machine shutdown for transient process events

Preformatted configuration for rolling element analysis

Bearing fault frequencies are well defined based on the geometry and rotating speed of the bearing in question.  The VES004 configuration wizard contains a database of common bearings.  When one of these bearings are selected, the fault frequencies are automatically entered into the wizard.

If the bearing cannot be found in the database, the fault frequencies can be calculated based on the bearing geometry and manually entered into the wizard.
