The selective calculation method has been successfully applied for several centuries due to its profitability. However, when calculating the failure-freeness in the case of fatigue fractures (often sudden), when there is a significant power relationship m = 10-15 for the super-cycle loading region between the strength (hardness, endurance limit) and the effective voltage, the reduction of the minimum component life will be 10-100 or more times. This is due to the unaccounted main part of the population. In our example, there are 104 50 = 9950 units of such parts, i.e., their potential failures. Therefore, for this case, the selective method is an intermediate stage of calculations.

The control of obtaining the predicted physico-mechanical properties of protective coatings of machine parts in a complex acoustic field by the method of electroacoustic spraying is carried out through the use of highly concentrated sources of electrical energy. The prediction of the physico-mechanical properties of the hardened surface of machine parts is made on the basis of the experiment planning methodology with non-orthogonal planning matrices. The adequacy of the obtained mathematical models was carried out using the criterion of adequacy of Fisher. Physical fundamentals of mass transfer of materials to a substrate in a complex acoustic field, realized through the transformation of longitudinal vibrations, to longitudinal-torsional, have been developed, while the amplitude of oscillation of the acoustic system is 5 to 15 micrometers. The use of longitudinal-torsional ultrasonic waveguides in this process and ultrafast cooling temperatures make it possible to form elements such as carbides, carbonitrides, and intermetallic compounds on the surface of a conductive material. The subsequent impact with a shift against the surface produced by the waveguide - electrode leads to irreversible microplastic deformations of the surface layer, which provide the specified parameters of surface quality and its physico-mechanical properties.

“…Mineral fertilizers from the X-TenderT unit are supplied under pressure to the loosening working bodies of the Cenius cultivator and, with the help of a special device, switch over to work according to the following technological schemes: 1 -100% of fertilizers are applied to the depth of soil cultivation by rippers; 2 -50% of fertilizers are applied to the depth of soil cultivation by rippers, and the other 50%superficially, which significantly improves the operation of the tillage fertilizer. [10][11][12] In addition, in the system of resource-saving technologies of the agroindustrial complex of the Russian Federation, soil cultivation machines with disc working bodies are widely used, after the passage of which the mulch layer required by agricultural technology is created. Disc harrows of the German company "AMAZONEN-WERKE" -"Catros" produced by JSC "Euotehnika" (Samara) and supplied to agricultural enterprises in Russia with a wide range of working widths in mounted and trailed versions with promising structural elements, also equipped with special equipment for fine processing soil with simultaneous application of mineral fertilizers when aggregated with a specialized large volumetric hopper for mineral fertilizers -X-TenderT [2].…”
