IMITATIONAL PHYSICAL MODELING OF A UNIVERSAL FORESTRY MACHINE
The Fourth Industrial Revolution, or “Industry 4.0”, is a concept of technological development, which involves the introduction of intelligent computer systems in machines and mechanisms in order to increase the efficiency of technological processes, increase the level of safety, as well as their partial and complete automation. The basis of this concept is the use of modern computer algorithms and artificial intelligence systems, the use of large computing power, coupled with the processing of large amounts of data (BigData), as well as the use of additive technologies (3D printing) in the production of machines and mechanisms. Internet of Things technologies are one of the main principles of Industry 4.0: thanks to the smart interaction of a large number of machines that are combined into one computer network, it has become possible to constantly exchange various data between them. This made it possible to perform centralized calculations, the results of which allow reaching a fundamentally new level of production, fully automating many technological processes, as well as increasing their efficiency and safety. Currently, there is an active implementation of Industry 4.0 technologies in various industries. One of the promising tasks is the creation of ready-made solutions for the use of these technologies in machines of the logging industry. In this paper, we consider the process of creating a simulation physical model of a forestry machine using Industry 4.0 technologies. The rationale for the selection of all structural components of the model is given, a method for creating a model is considered, which includes the stages of design, calculation, layout, prototyping, programming and manufacturing. Based on the results of pilot studies of control algorithms on the model, conclusions are drawn about the possibility of using these systems in full-size forestry machines.
