Abstract
The results of the construction of an information model of the process of soil cutting with straight-furrow oriented knives of dynamic action are giv-en. Bulldozer equipment and its main tasks are considered. A working hypothesis of the move-ment of the scraper and the vertically oriented knife has been formed. The working hypothesis is based on the fact that the movement of the spa-tially oriented knife will be carried out longitudi-nally - translationally, perpendicular to the trajec-tory of the movement of the working body. The dynamic movement of the knife will be carried out with the help of a self-oscillating hydraulic vibrator, the development of such a solution was implemented at the Department of Construction Machinery of KNUСA, the prerequisites were the work of the team, in particular, prof. Smirnov V.M. regarding the structure of the working body and prof. Baladinsky V.M. regarding the regulari-ties of creating dynamic movements of cutting elements of earth-moving machines. And also, based on the works of Khmara L.A., candidate in connection with the intensification of the mecha-nization of earthworks in construction. Their vec-tor movement and determination of the angles of application of the main cutting force to the corre-sponding angle α are presented. After constructing the movement vectors of the working body and the spatially oriented knife, a method of calculating the direction of the cutting force and the de-flection angle α was developed. Using vector sums and speed ratios ranging from 10:1, where the spatially oriented knife moves ten times faster than the blade, to 1:10, where the spatially orient-ed knife moves ten times slower. A graph of the determination of the angle α is plotted depending on the ratio of the blade feeding speeds and the displacement of the spatially oriented knife. The speed ratio is calculated and entered in the speed ratio table according to the angle α and the bull-dozer's gear ratio.
