Organization of technical service of machines under zone operating conditions provides for the possibility of determining the list of units exposed to climate effects and the estimation of zone correction factors to the consumption rates of spare elements during repair and maintenance [1].
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.
The article presents the results of experimental studies to determine the relationship between the electrolysis modes and the properties of electroplating coatings for mathematical modeling of the dynamics of the electrolytic process (MDEP), described by a system of ordinary differential equations due to the complex relationship of the kinetics of chemical reactions, hydrodynamics and mass transfer in the electrolyte flow, the kinematics of electrode plates, and the influence of the electric field of the "anode-cathode" pair on all these processes. At the same time, the experimental base was a series of full-scale experiments to restore the seats of the root supports of cylinder blocks with electroplated coatings. The final result of the research is the procedure for constructing an optimal resource-saving mode of electroplating, which is a zinc-iron alloy.
When solving the problems of increasing the reliability of automotive and tractor equipment during the regular repair period, a problem of adjusting the norms of the need for spare parts appears. The lack of recommendations for their determination, depending on the operating conditions, determines the need to deepen the analysis, development and refinement of techniques in order to clarify and adjust the normalizing factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
