“…Both of these schemes, their geometry and the forces on the milling feeder are fully described. To compile a mathematical model of the working process of a millingrotor snowplow with a paddle intensifier, the first design case has been taken into account, It will be more energyintensive, besides, according to this scheme, it is possible to immediately check the effectiveness of using the MRS with a bladed intensifier in the development of anomalous snow masses, as well as check the most rational layout of the MRS working equipment [3][4][5][6]. It is necessary to consider the MRS screw feeder scheme (Figure 1), in the middle of which, between the left semimill (1) and right semi-cutter (2), a bladed intensifier (3) is installed, in the form of a throwing drum with blades, which has an autonomous drive and rotation independent of the feeder.…”

“…The snow melted, changed its structure, looseness, stickiness, etc. It was decided to replace natural snow with a material that most closely imitates snow and has a reproducible constancy of properties, especially since recommendations were found according to which the starting materials were selected, namely sawdust, sand and paraffin, a mixture of which in a certain percentage proportion was imitating snow material [4,6,7,12]. The same materials were used in previous experiments, so the physical and mechanical properties of the material simulating snow did not differ from those known [1,2,13].…”

The article presents the process effectiveness evaluation of the throwing snow mass from the face into the operating area of the snowplow rotor-thrower by a milling feeder, when using a paddle type intensifier. During the operation of the milling-rotor snowplow, an operational problem sometimes arises, arising from an incorrectly set slope (angle of elevation) of the helical line of the milling feeder, due to which snow is thrown forward by it along the snowplow, forming an additional amount of snow for processing, which increases the overall energy costs for the development of snow and the movement of the machine in the snow massif and at the same time reduces the performance of the snowplow [1, 2]. The area of rational values of the design and operating parameters of the milling feeder and the bladed intensifier of the snowplow has been calculated. The process of efficiency increase of the milling-rotary snowplow (MRS) and its performance by adjusting the helix angle α and installing a bladed intensifier reducing the power of the working process will make it possible to perform work on clearing snow and ice formations using reduced number of machines, moreover in much less time. A more massive supply of snow mass to the blades of the rotor-thrower due to the use of an intensifier will lead to a decrease in the total energy costs for the snowplow working process. Therefore, by increase the working equipment efficiency of a MRS with the energy intensity decrease of snow development by selecting rational parameters for its design and workflow is the simplest and most effective way to rationally organize the workflow and improve machines of this type of snowplow.

“…It allows assessing the machine compliance degree with its functional purpose, combining technical parameters with working conditions. A modern bulldozer is a complex system that includes a number of subsystems united by structural and functional links [4][5]. It is advisable to analyze the efficiency of functioning and optimize the parameters of individual subsystems, taking into account the connections and restrictions imposed by the remaining subsystems, based on the methodology of system analysis [6][7][8][9].…”

“…A large number and difficulties in describing many of the parameters and relationships between them lead to the fact that only a part of them is involved in the mathematical modeling of the performance of a bulldozer. Depending on the specific goals, the main parameters of the bulldozer [8,9], the design features of various subsystems -the working equipment [10,4,11,12], the propulsion and transmission unit, and the propulsion system [13,14,15], the system control [13,16]. To varying degrees, the parameters of the operational background are also reflected -the developed soil, the bearing surface, the construction site, socio-economic and other factors [17,18], [19][20].…”

“…In order to simplify the analysis, it is assumed that there are no blunt areas on the cutting knives. The determination of the digging resistance components is based on the principle of superposition, all resistances are calculated separately for the middle and side sections, as was done in the study of spherical dumps [4]. When compiling the design scheme and determining various resistances, the features of the dump with variable geometry, identified in the analysis of geometric dependencies between its parameters and experimental studies, were taken into account.…”

The purpose of the work is to determine the rational parameters of a bulldozer blade with variable geometry, which provides an increase in productivity and an expansion of the bulldozer-terracer scope due to its universal adaptability of the cutting knife shape and the blade surface to the types and conditions of work. The existing studies of the interaction processes with the soil of specialized plough, for the most part, do not take into account specific features and do not allow a reasonable approach to the appointment of the main parameters of the dump with its universal adaptability. For this purpose, studies were carried out on the working process of excavating the soil with a blade of a new universal design, and above all, when digging the soil. The analysis of the ratios influence the central section length to the maximum working width, the inclination angles of the hinges in the longitudinal and transverse planes, and the rotation angle of the side sections on the variable geometric parameters of the blade, which determine its interaction with the ground, is carried out. At the same time, the theoretical dependences obtained based on the statics provisions of a granular medium with adhesion make it possible to analytically evaluate the dimensions and volume of the drag prism and the horizontal component of the resistance to digging with a blade with variable geometry. The study is funded by the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan (grant No. AP09260192), and is also the result of the Ph.D. dissertation of Aukenova B.K.
