Instrumental Analysis

Advantages

• Highly reproducible due to constant testing conditions
  
• Manifold sample geometries near to application cases
  
• such as pins of 4 to 20 mm diameter, rings (max. diameter 112 mm) Component testing feasible
  
• Qualitative assessment of materials under conditions near to practice

Parameters

• Testing load 0 ... 5,000 N
  
• Friction couple to be dissolved in cycles
  
• Rotation to the right/left up to 8,000/min
  
• Heating of the testing installation to about 300 °C
  
• Testing under inert gas, fluid or abrasive media
  
• Rotating motion can be overlaid by vibration
  
• Oscillation from 35° to 350°
  
• Stop braking upon electronic rotating mass simulation

Measuring variables

• Frictional moment (max. 10 Nm)
  
• in situ measurement of total abrasion
  
• Temperature
  
• Acoustic emission

Range of applications

• Materials development
  
• Generation of material data sheets
  
• Pin/disk testing according to DIN 50324
  
• Testing of friction couples at original parts vibrating in rotating direction whereby vibration is overlaid a very low speed value (amplitude and frequency can be selected), at increased testing temperature.
  
• Operational testing (stop braking) of materials for clutches and brakes
  
• Testing of friction couples whereby rotating direction is changed (moving about, hinges or plunger/ cylinder) by oscillating rotating motion
  
• Testing on impacts by abrasive media, Testing installation pin/ disk, or ring/ disk with cyclic dissolving and pressing against the frictional couple, thus, fresh abrasive material is getting to the frictional surface again and again.
