Published: October 2020

Abstract
One of the main ways to protect seed material from various diseases is treatment with chemicals. The most effective way to protect seeds from various diseases is wet etching with the simultaneous release of grain impurities. To develop a device for cleaning and etching seeds by wet density, studies were conducted to determine the minimum height of the loading hopper relative to the surface of the water solution of the etcher when transporting spherical grains to it in order to ensure that the surface tension forces are overcome. Practical experiments were conducted on throwing single grains of peas of the Vita variety (spherical grain) with a humidity of 14% into a liquid with a density of ρzh = 1000, 1090 and 1150 kg/m3. Sodium chloride salt (NaCl) was used to change the density liquid. To obtain more reliable information, the experiments were carried out in three-fold repetition. The temperature of the surrounding air and liquid of different densities ρzh was 20°C. It is established that when single pea grains fall 100%, the immersion in water (ρzh = 1000 kg/m3) occurs at a transport height h of at least 12.0·10−3 m. In the case of 100% immersion of pea grains in an aqueous solution of sodium chloride (NaCl) with a density of ρzh = 1090 and 1150 kg/m3, the minimum transport height h is 15.0·10−3 and 18.0·10−3 m, respectively.

Abstract
The main goal of the current research is to analyze the acoustic field of the threshing unit of a combine harvester. This research implements a numerical simulation of gas flow based on the Navier-Stokes equations with discretization of equations by the finite volume method. The finite element mesh used in the idealized model allows one to adequately analyze noise sources up to a frequency of 2500 Hz based on the broadband noise source models of Curl and Proudman. In this paper, the analysis of the flow around the threshing unit at two rotation speeds of 500 rpm and 980 rpm was performed in order to point out elements contributing the most to the noise environment of a combine harvester in operation. As a result of the analysis, the spectra of maximum acoustic pressure and intensity were obtained. Based on this data, there were obtained design refinement areas and areas of increased technological control of a typical thresher drum for the practical implementation in the noise reduction strategies.

Published: October 2020

Abstract
The interaction of the wheel and the rail is the physical basis for the movement of rolling stock on railways. In order to reduce the wear rate of wheel sets and rails, it is necessary to create a mathematical model for the interaction of the “wheel-rail” pair, on which one could look at various methods to reduce catastrophic wear. Currently widely used mathematical algorithms with many degrees of freedom of dynamic interaction of a pair of “wheelset rolling stock – railway track” have a number of disadvantages that affect the accuracy of the calculation results. It is necessary to first build the dynamic equations of dynamics in a basic fixed coordinate system, and then introduce a transformation into local coordinate systems. The algorithm proposed by the authors for constructing dynamic equations, taking into account the inclination and elevation of the outer rail over the inner rail, and the speed of the portable movement of the center of mass of the wheelset, allows to avoid all kinds of errors. In this paper, we describe an algorithm for constructing dynamic equations describing the joint motion of a wheel pair and a rail track, as well as an algorithm for solving the dynamic contact problem. The equations of translational and rotational dynamics of a wheel pair of a railway rolling stock (locomotive), the equations of motion of interacting bodies and communications are constructed. Based on the described mathematical algorithms, programs have been developed for calculating the forces of dynamic interaction in the wheel – rail system.

Abstract
The paper present modes of operation of 10(6) kV distribution networks, which are determined by the loads of consumers. The network scheme is based on an open circuit, which allows you to perform calculations for each 10(6) kV distribution line (feeder) separately. The calculation of power losses in the electric network is carried out by the method of average loads. The paper determines the integral characteristics of the operational parameters of the head branch, determines the parameters of the equivalent power loss of the feeder equivalent circuit, and the equivalent circuit determines the energy loss in the feeder. The paper compiles the equivalent circuit of the considered network section, calculated the parameters of the equivalent circuit elements and determines the total power loss in all linear sections. The paper presents an algorithm for calculating the steady state using the example of a feeder and shows the sequence of calculation of current distribution in the branches of the equivalent circuit.

Abstract
This article shows the principle of operation, experimental characteristics, comparison with other types of generators, functional diagrams of an electric generator set based on a field regulated reluctance machine. Attention is drawn to the high specific performance and favorable performance characteristics of these power generating sets. The simplicity of the design ensures high manufacturability of the electric machine, the non-contact design in combination with a “cold” winding-free rotor increases the reliability of the bearings and the entire machine, the ability to make the rotor massive (the rotor poles and the shaft are from one solid billet) significantly increase it strength and lateral stiffness. Also it allows obtaining high angular velocities and large moment overloads. Small control powers along the excitation circuit with a sufficiently high speed of this channel contribute to the achievement of high accuracy of maintaining a given voltage at favorable mass and dimensional parameters of the electric power plant.
Machining quality improvement and noise reduction of vehicle gears
Authors: Bagaiskov Yu 
Published: October 2020

Abstract
Gear honing is a method to ensure high quality of vehicle gear teeth lateral faces used primarily for batch and mass production. Gear hones are used for this operation. Both the service life of vehicle systems and the vehicle noise level depend on the gear’s parameters accuracy and machining quality. Effectiveness of using gear hones depends mainly on the hardness and elasticity modulus of their composite material. In terms of the elasticity modulus, gear hones can be hard and elastic, depending on the bonding agent type. Some increase in roughness of the gear teeth lateral faces was observed at decreased hardness of the hard gear hone material due to accelerated pitting of abrasive particles. As the gear hone material elasticity degree increased with simultaneous hardness decrease, roughness decreased significantly, even at an increased abrasive grit size, as a result of alignment of the abrasive grain peaks along the supporting surface, extended contact time of the grains and machined surface, contact pattern area and fullness of machining; a favorable grid of machining marks is available. Though removal of such coarse irregularities as dents and burrs by hard gear hones is more efficient. Overall reduction of the noise level of vehicle gears is observed, as well. Correspondence of the obtained experimental results to the suggested theoretic criterion of quality and machining fullness.
