Friction testing machine
Model 200
Link Engineering
The operation is based upon a one square inch sample of material which is contoured to rub against the interior or a simulated brake drum. By controlling either the normal load or the friction force while monitoring the other parameter under various thermal, speed, and load conditions, an assessment of the material's frictional properties may be made. Rubbing speed is controlled by a variable speed drive, load is controlled by a closed-loop servo system, and the temperature of the test drum is controlled by resistance heaters and a forced-air cooling system. Test results are presented in text and graphic form during the test, and presented in hard copy form at the completion of the test sequence.
A computer operating WIndows software performs all control and sequencing functions to capture, display, and report test data and to maintain a database of test sequences and test results. A self-standing enclosure is provided to house all control components which are pressurized to prevent contamination.
