Research on the application of new geometric shapes of bulldozer blades with typical

Abstract

The use of different types of bulldozer dump designs allows you to diversify the range of bulldozer equipment and ensure the most productive mode of operation. Additional structural features can also contribute to the accumulation of the volume of the drawing prism, for example, the expansion of the dumps due to additional side walls, an increase in the length of the blade blade or the area of the upper flaps. The article examines the dependence of the volume of the drawing prism, which accumulates in the blade, and directly affects the performance of the bulldozer unit. The authors investigated four types of bulldozer dump designs in order to increase the productivity of existing machines. The method of experimental studies performed on model samples of bulldozer dumps, designed on the basis of real ones, in accordance with the theory of similarity used in modeling, is described. The ratio of the masses of the prisms collected by different designs of experimental dumps has been established, and the purity coefficient has also been determined, reflecting the accumulation of material on the surfaces of the blade, indicating the additional cost of the power source of the machine. The study found that the use of new forms of bulldozer dumps is quite acceptable on existing equipment.
