The article presents a comparative analysis of the effectiveness of automated systems for recording the work parameters of autonomous locomotives. The relevance of the use of such systems is due to the prevention of defects at the stage of identifying possible malfunctions during the operation of locomotives during the inter-repair periods. So the used systems of parametric diagnostics of power plants of autonomous locomotives are considered. Also, for comparison, the experience of foreign research on the use of a diesel locomotive monitoring system is presented. Despite the fact that the existing automated systems for registering the parameters of diesel locomotives have a wide range of functionality that allows you to obtain typical dependences of the power of a diesel generator set (DSU) on temperature and pressure, these systems do not take into account the peculiarities of the flow of in-cylinder processes that can significantly affect the power of the DSU. The article proposes a method for monitoring and adjusting the power of the diesel engine during operation by registering the operating modes of the equipment and determining the actual power of the diesel engine by expanding the range of diagnostic parameters by installing additional sensors for registering measured values for the accuracy of monitoring and tuning the diesel engine and making timely decisions on maintenance and repair of locomotives. A block diagram of the recorder of operating modes with the location of sensors for measuring informative parameters and a diagram of connecting the recorder to the power circuit using the example of a shunting diesel locomotive CHME3 is shown. Software has been developed that can be additionally installed in the standard automated system for registering the parameters of the operation of the CHME3 diesel locomotive with subsequent data processing.

The article is devoted to the research of the of wind load effect on the aerodynamic component to the movement of a freight train. These findings contribute to a better understanding of the impact of aerodynamic resistance on the consumption of fuel and energy resources (FER) on train traction. The article shows the high significance of this problem for Joint Stock Company Russian Railways (RZD JSC). The conclusions were drawn from the analysis of statistical data on the routes of locomotive drivers, working on the Pallasovka-Verkhniy Baskunchak section, which is undergone to wind loads. The SOLIDWORKS application was used to design a train with a locomotive and gondola cars coupled on an embankment, and SOLIDWORKS Flow Simulation plug-in was used to simulate wind load, different in speed, varying from 0 to 90º. The values of the force of aerodynamic resistance to movement for the train as a whole and for each unit of the rolling stock separately were obtained. Using the methods of the theory of train traction, the influence of aerodynamic drag on fuel consumption for traction has been assessed. Based on the obtained values of the aerodynamic drag forces and patterns of air flow distribution, conclusions were drawn about the effect of loading a gondola car on an increase in traffic resistance. Conclusions are drawn about the effect of wind load on each unit of rolling stock in the train. It was found that when the wind is directed at an angle to the axis of the path, the force of the wind effect increases, compared with the case when the angle between the axis of the path and the velocity vector is zero. The experimental data on the increase in resistance from the wind load are confirmed by theoretical calculation, as well as practical processing of routes machinists. This article demonstrates the need for a separate regulation of fuel and energy resources in the event of wind loads, and may be useful in further detailed study of the aerodynamic drag of freight trains.

Measures to normalize the consumption of diesel fuel for the operation of shunting locomotives are an integral part of the efficiency of the use of traction rolling stock. Due to the presence of problems in the formation of the fuel consumption rate, such as the performance of the shunting locomotive, the loading and technical condition of the diesel generator set, the operating conditions of locomotives, it is necessary to improve the existing fuel consumption rate determining methodology. The article presents the results of studies of the operating modes of shunting locomotives, the parameters of the spread of the values of the operating time of the diesel generator set in the load mode for shunting locomotives of the TEM2 and TEM18DM series are given. A mathematical model based on the bases of machine learning models is proposed, taking into account the degree of loading of the diesel generator set and the technical and economic characteristics of the locomotive series. The task of the proposed model is to determine the fuel consumption of a locomotive by an iterative calculation method, where the input parameters of the model are the performance indicators of the locomotive. It is established that the method of forming the fuel consumption rate for performing shunting operations should take into account the degree of loading of the diesel generator set and the technical and economic characteristics of the locomotive series. According to the results of the implementation of the proposed model for establishing specific fuel consumption rates for the studied locomotives based on the results of their operation, the average indicators of specific fuel consumption by locomotives by the positions of the driver's controller are obtained. The proposed method allows us to take into account the actual degree of loading of the diesel generator set and establish the correct fuel consumption rate for a certain period of operation of the locomotive, which represents the practical significance of the work. The presented research results are the beginning of work on the development of an intelligent system for diesel fuel rate rationing for the operation of shunting locomotives.
