ABOUT INFLUENCE OF SPEED WORKING BODIES OF DIGGING MACHINES ON THE RESISTANCE FORCE OF SOIL CUTTING

Abstract

The processes occurring during high-speed cutting of soil is are considered. The dependence of the resistance force of soil cutting from speed of interaction, taking into account the compressibility of soil and the occurrence of wave drag forces is established. Analytical expressions for calculating the components of the total force of high-speed cutting of soils is given. The dependence of the energy intensity of the cutting process of the speed is analyzed and practical recommendations for the rational choice of cutting speed is given.
