Voice Coil With Real Time Stroke Control

N
The Smallest Controllable Stroke - 5um to 4mm, up to 300Hz

Real time stroke, frequency monitoring, and correction using LVDT.

N
High Reliability - Flexure Design

The flexural suspension guides the magnet assembly without
bearings.

N
Environmental Control, Surface Electrical Measurement

Humidity, temperature, inert gas, and electrical measurements for
real-life simulation.

N
High Frequency Response Force Sensors

Piezo based sensors measure friction force with ultra high accuracy at high frequency reciprocating test.

Fretting test module

High Speed Controllers

The Fretting Module Is perfect for testing surface damage that occurs between two contacting surfaces experiencing oscillatory displacement of a small amplitude.

Fretting test regimes
Test Debris
  • Debris formation from asperity contacts
  • Oxidation at contacting surface because of humidity, temperature, or chemical composition change
  • Oil, lubrication starvation regimes causing wear
  • Wear due to electric discharge
  • Repetitive collision between surfaces
  • Fatigue related cracks – onset of debris
  • Polymerization of organic materials at surface
  • Fine powdered debris – highly oxidized
  • Residual steady stage flow of debris
  • Diffusive wear
  • Melting wear
