Effect of the angles of the earth-moving machine moldboard on the cross slope of the graded surface

Abstract

Investigations of the effect of the moldboard angle, the earth-moving machine of the motor grader type, on the angle of the cross slope of the formed earth surface was carried out. It is established, that the slope in the cross direction of the surface being graded, depends on the angles of installation of the moldboard blade element. The slope of the surface being graded, is not affected by the dimensions of the moldboard and the construction of the earth-moving machine. Analytical and graphical functional dependences of the angle of inclination of the moldboard blade element to the horizontal plane are obtained, which are necessary to ensure a given angle of the cross slope of the surface being graded. The results of the research can be applied in the field of development and tuning of on-board systems for indicating and controlling the operating modes of an earth-moving machine.
