Abstract
A device to measure the influence of friction force on wear characteristics of a material surface comprises a case with a cover. A moveable element (MFE) of a friction pair is fixed on a shaft installed in the case or is made flat. A holder of another, pressed, element of the friction pair (NMFE) and a clamp which applies a regulated load on the NMFE holder are attached to the cover. The NMFE is fixed to a NMFE holder installed using separate piezo sensors for pressing force and friction force in a sensor holder, which is installed using two pairs of lateral piezo actuators and their preload devices in an actuator holder, which is installed using two pairs of horizontal piezo actuators and their preload devices in the holder, which is installed in the cover of the device with membranes.
