Improving the efficiency of technological machines in the interaction with adhesive materials at negative temperatures

Abstract

Abstract In this paper, the object of study is a technological machine that develops the cohesive ground. The MAXFLIGHT 04 anti-icing fluid is considered as a means of controlling the adhesion of the “soil-to-metal” system used in the operation of technological machines while developing moist cohesive soils under negative temperatures. The aim of the study is to increase the productivity and efficiency of technological machines in the developing wet cohesive soils at negative temperatures by reducing the soil-to-metal adhesion. Mathematical processing of the research results allowed us to obtain regression equations for two working conditions: a regression equation without using prophylactic agents to reduce soil adhesion and a regression equation using the MAXFLIGHT 04 anti-icing fluid. Using the obtained regression equations, the proportionality coefficient (the reduced friction coefficient f) was calculated. According to the calculation results, the values of the obtained proportionality coefficient depend on the shear plane of the temperature.
