Simulation of dynamic processes when a soil-throwing drum meets an obstacle

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.
