Machinery & Energetics

One of the main areas of technical operation of complex agricultural machinery is its effective functioning on the basis of modern technologies of ensuring reliability with the use of means of controlling the parameters of their technical condition. In complex agricultural machines, stand-alone equipment is provided, which, with the help of appropriate sensors, informs about the actual state of the system and transmits information to the control panel. Information on the technical state of the equipment is important for assessing the level of its reliability and decision-making, on the one hand, on its increase in design and production, and on the other hand, in order to ensure the working status during operation. For the analysis of the state of the technical level of machinery and equipment in the field of precision livestock breeding, automation and robotization, a patent review was carried out, which resulted in the selection of relevant information for the purpose of systematization, analysis and identification of trends in the development of this area. It is established that in the non-destructive research with the implementation of lasers of continuous radiation for the generation of resonant modes of high-order oscillations and the search for anomalies in interference bands in restored holograms and obtained by averaging over time, the application of ultrasonic excitation as a load is effective. Holographic interference with pulsed lasers, as it has been established, should be used for fatigue studies, as well as materials for durability when using the mechanical bend of a cutting element, which includes a vertically mounted screw with knives fixed to it. To obtain interference bands on the surface of the hammer or deck, laser radiation with two waves of different lengths is used. The implementation of the presented methodological approaches helps to reduce the production of defective products, prevents emergencies in the process of exploitation and creates the consumer's confidence in the high quality of agricultural machinery.
