High Frequency Reciprocating Rig (HFRR)

The purpose of this tester is to characterize friction under lubricated condition using a ball on disc configuration. This tester is particularly suited for evaluating low lubricity fluids like diesel and gasoline.

The system consists of a temperature controlled stage that houses the test plate. A reciprocating arm with a ball holder to hold the test ball is pressed against the test plate with a known force. The system reciprocates maintaining the required stroke length, frequency, load, temperature and humidity.

A piezoelectric force transducer senses the frictional force. The unit is computer controlled and uses the WinDucom Data Acquisition System to record the output parameters.
