MACHINE FOR TESTING FRICTION AND WEARING OUT OF MATERIALS Russian patent published in 2008 - IPC G01N3/56 

FIELD: testing engineering.

SUBSTANCE: machine consists of a platform and specimen and control specimen holders mounted on it, actuators for rotating them and a measuring system, consisting of a sensor of angular velocities and strain-gauge transducers, mounted on the axis of the control specimen, connected to a computer through an analogue to digital converter. The measuring system contains an extra unit for measuring displacement of the control specimen and unit for registering parameters of the surface of the specimens, electrical outputs and the rotation actuator of the control specimen are connected to a computer through a current sensor and current-pressure converter.

EFFECT: more functional capabilities.
