Run-Out/Vibration

When looking for the best way to measure run-out/vibration, there are a number of important factors to consider, the type of run-out or vibration (direction), the type of measurement system, and the installation environment. Selecting equipment that doesn't adequately meet your needs can lead to insufficient precision and increased man-hours during production. This site is designed to help those looking for a run-out/vibration measurement system discover the best way to do so with confidence.

How to Measure Run-Out/Vibration

Find the best measurement method and the right equipment to measure "Run-Out/Vibration".

Measurement of surface run-out of rotating object

Example Application: Run-out measurement of HDD surface

Optimal measurement system

Optimal measurement systemLaser Displacement Sensor

Laser displacement sensors can be used to measure the oscillation at a single point on a targets surface.

A
Rotation
B
Surface run-out
KEY POINTS
  • Vibration amplitude increases the further away from the targets center of rotation, which makes fluctuations in height easier to capture.
  • Vibration measurements must be performed at a sampling rate of at least ten times the targets oscillation frequency.
  • Multi-color confocal method
    Linearrity:From ±0.2μm
    Confocal Displacement sensor

Optimal measurement system

Optimal measurement systemLaser Displacement Sensor

Laser displacement sensors can be used to measure the oscillation at a single point on a targets surface.

KEY POINTS
  • The peak-to-peak value of the run-out can be calculated by using a peak-to-peak hold or a similar function.
  • Vibration measurements must be performed at a sampling rate of at least ten times the targets oscillation frequency.
  • Multi-color confocal method

Measurement of other run-out/vibration using a 2D laser displacement sensor

Example Application: Residual vibration measurement of robots

Optimal measurement system

Optimal measurement system2D Laser Displacement Sensor

A laser beam that has been expanded into a line is diffusely reflected from the surface of the target. This reflected profile is formed on the HSE3-CMOS and by detecting changes in the position and shape of the reflection, it is possible to measure targets run-out.

KEY POINTS
  • When measuring with a 1D laser displacement sensor, the peak cannot be captured at all times if the peak point shifts to the left or right. The peak point can be tracked at all times by using a 2D laser displacement sensor.
  • Measurement must be performed at a sampling rate of at least ten times the oscillation frequency.
  • 2D Triangulation Method.
    In-line Multi-point measurement.
    World's Fastest sampling rate at 64,000 images/sec.
