Result Interpretation

Single-Plane Rigid Rotor Unbalance Vibration Amplitude calculator computes Vibration Amplitude in m using the defined engineering formula and the input values provided. Vibration Amplitude is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Unbalance Mass = 0.002
  • Eccentricity = 5.0E-5
  • Operating Speed (rad/s) = 314.159
  • Bearing Stiffness = 1000000
  • Equivalent Damping Coefficient = 600

Expected Result:

  • Vibration Amplitude = 4.937E-6

Engineering Interpretation:

Under the given input conditions, the calculated result is: Vibration Amplitude = 4.937E-6 m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
