Repair of agricultural machinery is one of the most important issues related to maintaining the efficiency of the fleet of vehicles used in the agricultural sector of the country. High equipment with high-performance machines and mechanisms obliges modern repair production to raise its technical level of repair technology, to improve in every way the organization of production, to expand the technical capabilities of production by introducing new technology and advanced technology. Mathematical modeling based on the results of a sample of observations on the current evolution of the galvanic process development for a given technological product (cylinder block bearings) using the third-order spline approximation method, continuous interpolation of the state vector of the galvanic process is constructed. The method of constructing a mathematical model of the electroplating process allows us to raise the question of finding the optimal electrolysis mode in the process of restoring the seats of the engine bearings core blocks. In this case, the optimal electrolysis mode is understood as an electrolytic process, which, on the one hand, provides the specified quality indicators of electroplating, and on the other (simultaneously), minimizes the energy and material costs for its practical implementation. The results of operational tests confirmed the high wear resistance of the electroplated coating, which exceeds the wear resistance of the base material by 20-30%.
This article discusses the design of modern wheel-transport vehicles, in which the problem of reducing the level of vibrations and shocks arises, since the quality and performance, reliability and durability of the operation of machines, devices and equipment depend mainly on the resulting fluctuations during their operation. Also, solutions of problems concerning the limiting properties of solid-state systems for cases of harmonic and shock effects are discussed. The design model of many technical objects is a solid body, which is onboard radio electronic equipment (REA). For the selected model of a solid body, a system is designed for the vibration isolation of a block, at s points of which there are electrical radio-sensitive elements that can withstand a given limiting vibration acceleration. The synthesized vibration-proof system is implemented with the help of linear passive elastic-damping suspensions and active elements, which represent an ideal servo-mechanism.
