Traction Machine On The MFT Platforms

Main Features:

• Downforce 0 to 200N (platform dependen – up to 3000N)
• Speeds 6 to -6 m/s (higher speeds available)
• Electrified – DC, AC, and Voltage
• Capacitive force sensors for friction sensitivity
• Temperatures up to 180 °C
• Multi-function platform allows for more tests on the same platform 

What is a traction test?
The Traction Machine is a widely used tribological test in which the rheological and friction properties of lubricants are evaluated under controlled conditions. During a traction test, two rotating surfaces (often ball and disc) are brought into contact under a controlled load. These surfaces are then moved relative to each other with increasing sliding/rolling ratios. The test measures the coefficient of traction and, if necessary, also performs a Stribeck curve analysis at various loads, sliding speeds, and environmental conditions. Typically, lubricant film thicknesses or the structure of tribofilms are measured, but pressure-viscosity coefficients of fluids are also measured.

Rtec Instruments Solution—The next-generation traction machine was designed with versatility in mind. It uses two independently controlled closed-loop high-power servo drives to provide a wide sliding-to-rolling ratio. Synchronous or asynchronous operation at the contact surfaces is possible. Depending on the model selected, normal forces of up to 100/200/3000 N can be applied for any conceivable or application-specific traction and Stribeck curve. Several environmental chambers are available for the mini traction testing machine, ranging from cryogenic temperatures to 180°C.
