In the article, within the framework of the preparation of the instrumental base for revealing the dependence of the force parameters, namely the resistance to cutting of durable snow-ice formations (DSIF), engineering of the measuring converter is accomplished. The relevance of the article is due to the need to implement the program “Socio-economic development of the Arctic zone of the Russian Federation for the period until 2020” and the implementation of the strategy. It entails the development of the new working bodies of special machines for aerodrome-technical support, made on the basis of a disk cutting tool. At the design stages it is necessary to know the force parameters acting on the working body. The conditions for carrying out the laboratory experiments to study the process of interaction of the disk cutting tool with PSLO are described. The process of choosing the place of a strain gauge sticker from the point of view of necessary deformations and the way to assemble them into measuring bridge circuits are shown. The conclusions about the correctness of the selection of the material of the strain gauge element have been made. The hypothesis on exclusion of mutual influence of measured components against each other has been confirmed. The calibration coefficients for converting the voltage into a force value for each component of the cutting force have been received. The importance of calibrating the measuring converter before conducting the next experiment is emphasized. This work is a continuation of a series of work on experimental laboratory studies of the processes of interaction of a disk-cutting tool with DSIF, for a number of years, conducted at Siberian Federal University.
Keywords: snow-ice formations, disk cutting tool, power parameters, ice, radius of curvature of the working edge.
