Purpose. For testing materials for friction in a wide range of sample sliding speeds over a wearing surface.
Scope: mechanical engineering.
Advantages. As a result of the analysis of domestic and foreign literature and patent information, it was found that the minimum sliding speed that can be achieved by modern methods and equipment for friction testing is 2 mm/s. At the same time, the proposed device allows testing in the speed range from 10-5 mm/s to tens of millimeters per second.
Technical and economic effect. Since the device is proposed for testing during fundamental research, it is quite difficult to establish any indicators of the economic efficiency of its implementation. The economic attractiveness of a particular research work depends primarily on the market size on which it is planned to promote the results. The device only provides a fundamental opportunity to carry out work.
Description. A device is proposed that allows testing materials for friction in a wide range of sample sliding speeds over a wearing surface. Moreover, the minimum possible speed is much less than 1 mm/s. This allows for various studies in the field of tribology and tribotechnics.
