Oscillating friction-measuring instrument

Wear tests of material specimens

Operating principle

The specimens for the test are screwed to the piston rod by a specimen support, and slide in oscillating movement on the mating surfaces. The mating surfaces are pressed to the specimens at a defined power, and guided by a linear guiding system in accordance with the wear pf the specimens.

The measuring-value recording and editing program determines:

  • Friction force
  • Contact force
  • Wear curve
  • Sliding speed
  • Test duration
  • Wear factor

 

Advantages when compared to conventional friction-measuring instruments:

  • Near-praxis wear tests at oscillating movement
  • Simultaneous measurement at several specimens
  • Wide variation range of the test conditions
       - Contact force
       - Sliding speed
       - Temperature of the mating surfaces
       - Gases: air, H2, N2 and natural gas
  • Stroke 130 mm
  • Max. mean sliding speed 6 m/s
