Investigation of the Interaction Process with the Environment of a Bulldozer Bladow with Variable Geometry

Abstract

The purpose of the work is theoretical and experimental confirmation of rational parameters, a significant range of rational use and efficiency growth of bulldozers-terrasers due to the installation of a universal, adaptable to variable working conditions of the blade with a variable geometry of its profile. Experimental studies have confirmed the correctness of the assumptions made when deriving analytical dependencies for determining the volume of the accumulated ground prism, as well as the components of the horizontal resistance to cutting and digging with a blade with a variable geometry. The experimental and theoretical dependences obtained as a result of the research made it possible to develop a methodology for determining the main parameters of a blade with a variable geometry, taking into account functional limitations. The article shows the stages of theoretical and experimental results of checking the dependence of the counteraction forces (their horizontal and vertical components) on digging and generating a drawing prism of the material being developed on the defining parameters of the blade with variable geometry (angles of capture, tilt and cutting, blade width, etc.). The proposed method for determining the main parameters of the blade with variable geometry allows you to choose them taking into account the universal purpose of the blade, the results of the research, the existing geometric dependencies between the parameters and various functional limitations.
