The paper considers the stages of designing mechanical disk hopper loading devices, during which high reliability and the required performance of systems for automatically loading asymmetric parts of the shape of rotation bodies into modern technological equipment will be ensured. The main tasks of each stage and ways to solve them are shown, which contribute to improving the reliability and ensuring the required capacity of the hopper loading device for parts with asymmetry. The solution of the tasks in the specified order allows, at the early stages of design, to develop the design of the bunker loading device that is optimal in all respects and does not require expensive investments in the creation of prototypes for testing to evaluate its performance.

It is proposed to use a loading and transport unit based on a stacker with a sequential structure manipulator, a rotary platform and a universal pincer grip, which will increase the service area relative to the forklift, the functionality of the loader, reduce the time spent on maneuvering the chassis by the loader up to 12 % and increase the productivity coefficient of the loading and transport unit up to 0.7.

As a result of the research the design of the loading and transport unit has been developed. The technological process of loading, transporting and laying barrels of oil in warehouses is proposed. The degree of mobility of the handling mechanism of the loader is calculated according to the formula of Somov-Malyshev-Chebyshev. The kinematic analysis is carried out, and it is calculated the theoretical working area of the service of the output link of the loader's lifting body, formed in the Mathcad software package.

Rolling stock braking devices differ from devices used in other types of transport due to the presence of a transmission mechanism in the drive. The multiplicity of the clamping mechanism provides not only an increase in the clamping force in the working pairs of the brake, but also causes an increase in the oscillatory process in the tribocontact of the braking devices. The article presents analytical dependencies for determining the angular movements of the lever and brake pad of the clamping mechanism of the braking device. Using mathematical modeling, it was found that with an increase in the frequency difference between the lever and the brake pad of the clamping mechanism of the power device, the number and amplitude of the rebound of the brake pad from the working surface of the disc increases, which leads to a decrease in the stability parameters of the brake performance.

The developed design methodology makes it possible to evaluate the operational parameters of stability, efficiency and energy intensity of newly designed and operated discpad type braking devices with various clamping mechanisms. A distinctive feature of the developed methodology is the consideration of the number, size and geometry of the placement of the clamping elements of the braking device, in contrast to previously known calculation methods. The performed calculations of the operational parameters of braking devices with poly-clamping elements, according to the proposed methodology, made it possible to conclude that the brake mechanism with two clamping elements has greater efficiency and stability than the serial mechanism and the proposed alternatives with the same geometric parameters of the brake disc and pads. Another feature of the technique is the relationship between the operating parameters of the brake and the heat transfer capacity of the cooling unit of the device. The calculation of the temperature field and the ability of heat transfer from heated surfaces to the external environment is based on the method of determining the residual temperature, the distribution of temperature fields over the thickness of the disc and the developed multilayer thermal model "ventilated brake disc – external environment". As a result of calculations, the power device with two clamping elements has an increased braking torque in the center of pressure relative to the serial brake mechanism by 29.7%. The coefficients of stability and oscillations of the braking torque of a power device with two clamping elements increased relative to the mono-clamping brake mechanism by 14.1% and 3.6%, respectively.

As a rule, gear grinding is the final method of processing all more or less precise gears. It allows to ensure high accuracy of the tooth profile and relatively low roughness specified by the drawing. It is beginning to be used for the manufacture of hardened gears, starting from 7 to 2 degrees of accuracy. The paper deals with the formation of roughness when grinding teeth, calculations are made of the effect of cutting speed and wheel grain size on the critical penetration depth and surface roughness, and the results of the calculations are presented in graphic material. The dependences obtained have been verified during experimental studies and can be recommended for predicting the roughness of the machined surface during gear grinding.

The paper discusses measures for the coordinated development of the interacting rail infrastructure and sea modes of transport on the approaches to “Olya” port in the conditions of the projected growth of cargo flows along the North-South transport corridor. The prospective volumes of export traffic along this corridor have been determined. The capacity of railway approaches to “Olya” port is being evaluated and proposals for the development of railway infrastructure in accordance with the planned port capacity for the development of the entire volume of cargo traffic are being considered. If each event individually does not give the expected effect of increasing the capacity, then it is necessary to consider a set of measures to achieve the required capacity of the infrastructure of interacting transport modes. The analysis of foreign and domestic experience is carried out to ensure effective interaction of various transport modes. The experience of organizing significant export cargo traffic to the ports of the South of Russia in a new direction is applied, taking into account the peculiarities of the operation of the object under study. To solve the tasks set, a methodology for calculating the throughput was used, as a result of which options for increasing it on a cargo-stressed section were proposed and the best option was selected, ensuring high reliability of transportation, timely delivery and unloading of goods.

It is analyzed the introduction of connected trains, increased mass and length on the railways of the Russian Federation. The possibilities of their operation in some countries are also considered: the USA, South Africa, China, etc.

The practice of driving connected trains and increased mass and length creates opportunities for further growth in freight turnover, increasing the throughput of existing railway sections, allows you to quickly respond to changes in traffic volume without increasing the number of trains or refusals to fulfill orders, which contributes to an increase in the level of customer focus.

The main factors limiting the through movement of long trains and trains of increased mass using the existing rolling stock are the short length of the stations' receiving and departure tracks and the insufficient available capacity of the traction power supply system on certain sections of the railways.

The growth of the population of large cities in Russia leads to a deterioration in the environmental situation caused by an increase in environmental pollution from the use of public and individual transport.

This paper gives brief analysis the algorithms performance dependence for computing the fast Fourier transform on the volume of processed data. All existing algorithms in work do not take into account hardware capabilities of computing devices in full. As a result of non-optimal use of processor memory for different data volumes, the number of operations can greatly increase. Visual analysis of graphs dependence FFT performance on its size allows us to suggest a piecewise continuous nature of this dependence and the reasons for various noncontinuous sections of the graph. When developing implementations of algorithms that use FFT, it is necessary to obtain a method for numerical evaluation of the boundaries of the graph sections. The method under development allows to determine with a high degree of reliability the boundaries of sections on the FFT performance dependence graph, on which the derivative of the graph changes. Algorithms of digital signal processing that uses FFT, it is desirable to develop in such a way that the FFT size does not exceed the boundary determined by the data cache size of the first level of memory cache.

General measurement informational processing algorithms do not always provide the necessary accuracy of assessment under external influences and require large computing power, which is difficult to implement under conditions of restrictions on the weight and size characteristics of UAVs transport. The use of algorithms for dynamic estimation of the UAV angular orientation based on an adaptive model in combination with the use of multilayer neural networks of direct propagation makes it possible to reduce the error in estimating the parameters of a dynamic system without a significant increase in computational costs. The paper presents the synthesis of a UAV orientation estimation system with a multiparameter neural network identifier, which makes it possible to improve the estimation accuracy in comparison with the classical Kalman filter.

One of these structures most susceptible to external influences are bridge structures across water barriers. The paper considers many influences of various nature. The most significant ones are estimated evaluated in terms of probability of their occurrence and the ability to lead to a complete failure of artificial structures.

When a railway bogie passes through curved sections of the track, significant pressure forces of the wheel flanges on the outer rail thread arise, which lead to increased resistance to movement and intense lateral wear of the contact surfaces. The reason for this is the formation of large values of the angles of the wheel’s collision on the rails; therefore, to eliminate them, controlled devices are used to ensure the radial installation of the wheelset axes in the curve. However, the shortcomings of the known systems of controlled turning of wheel sets do not allow the full use of such systems on traction rolling stock. To solve this problem, the paper presents a modernized design of the axle box of the electric locomotive. The performance evaluation of the proposed node was carried out according to the results of strength calculations using the finite element method in the most unfavorable operating modes of the box. The analysis showed that the modernized unit meets the requirements for structural strength.

It is proposed a method for improving the energy efficiency in traction motors of the autonomous locomotives through the use of discrete-adaptive control of the operating motors` number in traction, which makes it possible to account the higher voltage values of the traction generator, as its result of losses depends on the reduction the current load. As a result of using the proposed adaptive control system, the operational efficiency of traction motors, according to preliminary estimates, will increase by 10%, which contributes to an increase in the fuel efficiency of the transportation process.

The paper proposes three-dimensional model of the design of an improved sand supply system using the effect of vibration liquefaction using a one-way piston pneumatic vibropulsator for smooth continuous regulation of the sand amount from the sandbox nozzle body and the ejection use of an additional amount of air through a gas jet injector to increase the ejection rate of the sand-air outflow mixture with separate independent supply of compressed air to the injector. The results of modeling the transportation of a sand-air mixture in order to determine the dependence of the outflow rate and mass flow rate of compressed air on the pressure in front of the working nozzle of a gas-jet injector for two different diameters of the nozzle flow section of 3.9 and 5 mm are presented. According to the results obtained, to implement the regulation of the speed of transportation of the sand-air mixture by controlling the pressure of the compressed air supplied to the working nozzle of the gas-jet injector, in order to compensate for losses due to various resistances in the sand supply system, it is more rational to use a nozzle with a diameter of the passage section of 5 mm.

Provides an overview of modern automated systems used to measure the diameter of a car wheel and proposes a classification system for such systems based on the kinematic features of relative motion within the source-receiver-object system. It is predicted the main features of measuring systems are shown and the features of future measuring devices have not used in railway transport. The example of measuring the wheel diameter shows the calculation of the main characteristics of the position to control the diameter of the car wheel as part of a wheel pair under the conditions of placing the position on a production line or storage track.

The intensity of heat removal by convective heat transfer from ventilated brake discs of wheeled vehicles is directly affected by the amount and passage time of the air flow through the ventilation apparatus. The more intense the air flow at the inlet and slower at the outlet to the ventilation unit, the more intensively the cooling of the brake disc will take place. It is possible to slow down the speed of air wind passage by creating artificial obstacles or by switching from laminar to turbulent flow regime. The research methodology proposed in this paper is able to characterize the mechanism of places` formation of high and low pressure in the ventilation duct and the occurrence of vortex flows during the turbulent flow of the air flow.
