The problem of combating forest fires is very relevant to this day. The development of machines designed to extinguish and prevent uncontrolled forest fires, especially in waterless areas, is the most important area of scientific research. The article presents scientific research on simulation modeling of the interaction of a soil-marking drum with obstacles of two types: stones and logging residues. For the study, a simulation method was used in the 3D-CAD environment of the SolidWorks Simulation system, which made it possible to conduct a virtual experiment of a solid model and determine the behavior under static and dynamic loads that occur in emergency situations. The purpose of the work was to develop a 3D model of a soil-throwing drum machine for extinguishing and preventing forest fires to conduct simulation studies on a virtual stand to determine the dynamic loads in contact with obstacles of the soil-throwing drum blades based on the created solid model. For the process of studying the soil-marking drum when encountering obstacles in the form of logging residues and stony inclusions, an imitation virtual stand was created. The paper presents the results of the analysis of data obtained on the basis of simulation modeling.

Introduction. An increase in the efficiency of snow removal work is due to an improvement in the characteristics of all components of this process, however, the creation of fundamentally new design schemes for snow blowers allows us to make qualitative changes in the problem of winter maintenance of roads, residential areas, etc. Materials and methods. A description of analytical studies of the dependence describing the design parameters of the feeder cutter for a rotary-milling snow blower is presented, on the basis of which the concept of a fundamentally new design of the feeder for a rotary-milling snow blower is formed. The description of the mathematical model of the presented design of the feeder is given.The structural scheme of the vertical cutter of the feeder of the rotary-milling snow blower is presented. Described are the main assumptions made in the compilation of the design scheme for the operation of the vertical cutter of the feeder of the rotary-milling snow blower. Equations have been obtained that describe the movement of a group of snow particles transported by a vertical mill and interact with each other in the process of movement, analytical dependences of the forces of normal reactions of the working elements of a vertical miller on its design and technological parameters.

Currently, the most common way to prevent and extinguish forest ground fires is laying of mineralized strips and ditches using forest plows, milling strip-laying machines and soil throwers. However, fire-break making soil throwers are not equipped with devices for removing the ground cover with combustible plant residues from the soil flow supplied to the fire zone when extinguishing forest ground fires, which significantly reduces the efficiency of the machine. Augers with a hydraulic drive are promising, which allow removing the ground cover, however, additional studies of kinematic and dynamic parameters are needed. The purpose of this work is to improve the quality of cleaning the flow of soil from the ground cover supplied to the edge of the fire by a forest fire stripper by substantiating the parameters of the auger working bodies. The analysis of literary sources showed that it is advisable to use modern mathematical models of the interaction between an object and the environment, based on the particle dynamics method, in the development of a forest fire soil-throwing machine. A new design of a forest fire soil thrower with auger working bodies, which are designed to remove the ground cover, is presented. A simulation model of the working process of auger working bodies using the particle dynamics method was compiled. A basic computer experiment was carried out to clean the soil flow from the forest litter. It has been established that pressure in the hydraulic motor decreases approximately exponentially, and the rotational speed of the working body also increases approximately exponentially up to 4 rpm during the acceleration of the working body. The interaction of the working body with the stump led to the appearance of a negative braking torque of up to 4.5 kNm. As a result, the rotational speed of the drum decreased from 4 rpm to almost zero. With a decrease in the rotational speed, the pressure in the hydraulic motor of the drive of the working body increased to 12.5 MPa. The auger working body provides approximately the same cleaning efficiency of the soil flow with a ground cover thickness of up to 20 cm, while the cleaning completeness is at least 0.86, and the power consumption is not more than 8 kW
