“…Authors [25] state and confirm with their research that significantly less wear of samples is subjected to hardening and boronization compared to steel in the normalized state, which proves the justification of these treatments as protection against wear of parts of agricultural machinery. The obtained research results are confirmed by [26] with the hypothesis of a positive effect of strengthening (pointed) cultivator hoes with wearresistant coating. In the process of work, the protected blades of hoes "in segments" get an oblong shape, and the wear of their blade wings is reduced by 32%, and the front part by 70%.…”

The paper presents the results of comparative wearing of cultivator hoes protected with two different materials with regard to the lifespan of the blades. During the operation of the hoes outside the track of the tractor wheels with protected blades of materials M1 and M2, equal wear of mass and surface was recorded. The hoes lost an average of 0,563 g/ha cultivated area or an average of 119,46 g with a standard deviation of 2,876 when working with both blades in compacted soil (in the tracks of tractor wheels) protected by M1 material. For hoes protected by M2 material, the average loss was 0,566 g/ha of cultivated area or an average of 120,10 g for the research period with a standard deviation of 4,609. Both materials in the most difficult working conditions showed equal resistance to wear and retention of the initial shape of the hoe.

The relevance of the study is to develop an effective system for controlling the pressure in the air supply in motorised breathing apparatus to ensure effective protection of employees from dangerous aerosols and improve their health. The goal was to create an automated air pressure control system in a motorised breathing apparatus using a proportional-integral-derivative controller. For this purpose, the simulation method was used. In order to avoid unforeseen situations of deterioration of the level of protection, the structure of the pressure control system of a motorised respirator has been developed with the selection of the appropriate controller based on the obtained dependences of the influence of the parameters of the breathing mode and the amount of pressure in the under-mask space of the respirator, which ensures an appropriate comfortable mode of operation. This allowed developing a simulation model with a PID controller that would provide the appropriate pressure values within the permissible limits (50-370 Pa). It is proved that the proportional-integral-derivative controller maintains the pressure in the respirator mask within certain limits both with an increase and with a decrease in the control signal, preventing excessive fluctuations in the controlling variable, which leads to an extension of the service life of the filter elements and a reduction in electricity consumption for the operation of the fan motor. Based on modelling the operation of the pressure control system in different modes of operation, it is shown that when using a PID controller with defined parameters, the system provides compensation for changes in air

The relevance of the study lies in the need to investigate the dependence of the force applied to the spring tooth on its parameters, which is an important task due to the widespread use of spring teeth in agricultural implements, such as balers, reapers, rakes, etc. The purpose of the study is to establish an analytical description of the spring tooth deformation depending on the amount of applied force. For this purpose, the theory of bending rods from the resistance of materials was applied, without simplifying it, as is common in construction, where the deflection of a beam is small compared to its length. The calculation is based on the well-known dependence of the curvature of the elastic axis of the beam (tooth) on the applied moment and the stiffness of its cross-section. The study considers a cantilevered tooth, which at the point of pinching is a spring with several turns, followed by a smooth transition to a rectilinear shape. The tooth is divided into two parts along its length: curvilinear and rectilinear. Calculation of the deformation, i.e., finding the shape of the elastic axis after the action of the applied force, is carried out for both parts separately. The need for this approach is dictated by the fact that the curvature of the elastic axis of the tooth in the free state changes abruptly from the stable value of the curvilinear part to a zero value of the straight part. The main result of the study is to find the shape of the elastic axis of individual parts of the tooth under the action of the applied force and combine them into one whole. This helps to determine the amount of movement of the free end of the tooth depending on the amount of force applied to it. The application of the obtained data can help in the development of more efficient and productive agricultural tools, and increase their durability and efficiency when interacting with the soil
