- W4200224653 abstract "Ensuring the competitiveness of enterprises of the forest complex is largely due to the level of reliable and high-performance equipment use, since this achieves a significant increase in the efficiency of timber harvesting and processing. At the same time, the required level of reliability of logging machines is largely determined by the performance of their functional units that carry out the basic technological operations. Accordingly, the development and implementation of ways and methods to improve the performance of functional units of machines is important when creating promising models of the specified equipment. This requires an analysis of the prospects and technical possibilities for improving the main mechanisms and units of logging machines and the factors limiting their performance. In order to improve the performance of machine functional units, it is essential to ensure the coordinated provision of favorable levels of a significant number of design and technological parameters. In particular, it is advisable to optimize the nature of the relative movement of the friction-contacting surfaces of the parts and reduce the loads acting on them. This is due to the fact that these factors determine the wear resistance and friction resistance, as well as the thermal mode of the machine operation, the stress state of the functional surface layers and the strength of the fixed joints. At the same time, the influence of operating conditions, the wear intensity and service life of the objects under study should be taken into account. This approach is due to the fact that tribotechnical units of logging machines perform their functions under the action of high shock, cyclic and vibration loads, in a wide range of harsh natural and climatic conditions characterized by low temperatures, high humidity, and the action of chemical and abrasive media. All this should be considered when justifying effective ways to improve the performance of functional units, including manipulators of logging machines, and achieved through regulated directional control of the properties of surface layers in the design and manufacture of friction-contacting parts. The paper substantiates the need to create scientific and engineering foundations for improving the performance of functional units and working bodies of machines, as well as achieving the required performance, durability and reliability. For this purpose, the tasks of further research aimed at obtaining information, the absence of which makes it impossible to create domestic import-substituting equipment, are clarified.
