METHOD TO DETERMINE STRENGTH CHARACTERISTICS OF MATERIAL AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC G01N3/46 

FIELD: machine building.

SUBSTANCE: device comprises a body with an electric motor and a reducer inside it; two parallel columns fixed on the body with a cross beam installed on it as capable of displacement along them together with mechanisms of its fixation on the columns and a tool fixed on it; a tool head, a mechanism of tool installation, a mechanism of tool feed and removal from the sample surface, a metre of normal movements of the tool, a sensor of normal force, a mechanism and a table for installation and thermal stabilisation of the sample; a mechanism of normal loading of the tool; an automated system of setting of a loading and unloading program, reading, recording and processing of test result information together with a personal computer. The device is additionally equipped with a mechanism of tangential displacement of the sample; a mechanism of sample rotation in the vertical plane; a mechanism of fine displacement of a sample in a vertical plane; a mechanism of accelerated displacement and fixation of the tool; a sensor for measurement of a tangential force; a mechanism of vertical displacement of the cross beam. The substance: a program is used to select a type of research and its completion from possible several automatically realised on one and the same device, such as strip-chart recording or stylus method for assessment of sample roughness; assessment of microhardness of sample surface; assessment of energy of plastic deformation activation; tribometric technique; forecasting of the residual resource; strip-chart recording and stylus method of sample surface rippling, and the selected research is carried out with the help of the device.

EFFECT: expansion of technical capabilities, simplification and acceleration of operations.
