Empirical assessment of thermodynamic processes of a turbojet engine in the process values field using vibration parameters

The results of the calculation of the kinematic parameters of the movement of a freight train by a graphical method on a virtual hilly section of a high-speed railway when moving without stops and with stops at an intermediate and final station are presented. The values of energy efficiency indicators of UzTE16M3 diesel locomotives were obtained in quantitative and monetary terms when driving a freight train of a unified mass of train. The research results are presented in the form of tabular data and will be implemented by specialists of the locomotive complex in substantiating the efficiency of the transportation work of UzTE16M3 diesel locomotives in real operating conditions.

“…The specified diesel locomotive refers to a land-based wheeled vehicle with a power energy plant [3] -this is diesel 1A-5D49 of the third version, which is characterized by high efficiency with specific fuel consumption at rated power mode (2206 kW) equal to 208 g/kW-h and hourly fuel consumption of idle mode -14 kg/h. An analysis of scientific research by domestic scientists [4][5][6][7][8][9][10][11] and scientists from far abroad [12][13][14][15][16][17][18][19][20][21][22][23][24], aimed at studying the efficiency of various types of locomotives, their systems, units and apparatus in the conditions of operational activity of railways and of railway transportation of goods the organization, indicates that no the a sufficient degree of study of issues related to the justification of the kinematic parameters of the movement of freight trains and the parameters of the energy efficiency of locomotives on virtual and real sections of railways of varying complexity, including of Uzbek ones.…”

A program algorithm and a method for producing (performing) traction calculations are proposed, based on geometric constructions of changes in the speed and time of train movement along the track, relying on the specific resultant forces of the train in the travel track of rolling stock. Calculations of the kinematic parameters of the movement of a freight train on a virtual hilly section of the railway were carried out using a graphic-analytical method when moving with stops and without stops at the intermediate and final stations. The values of the energy efficiency indicators of UzTE16M3 diesel locomotives when driving a freight train with a minimum train weight in quantitative and monetary terms are substantiated. The numerical results of the research are obtained in the form of tabular data, which specialists of the locomotive complex can use when analyzing and assessing the efficiency of the transportation work of UzTE16M3 diesel locomotives under real operating conditions.

“…A comparative analysis of the result of some studies [6][7][8][9][10][11][12][13][14][15][16][17][18] of foreign scientists in recent years, based on system analysis and generalizations of previous methods and techniques, revealed different approaches to the integrated development of design, organizational, technical, and technological measures to improve the efficiency of aircraft and railway transport in the normal mode of operation.…”

The present research paper provides the outcomes of calculating the kinematic parameters of freight train movement using the graphical method on a virtual hilly section of a high-speed railroad when moving without stopping and with stops at the intermediate and end stations. Values of energy efficiency indicators for UzTE16M3 diesel locomotives in quantitative and monetary terms when driving a freight train of a unified train mass are obtained. The research results are presented in the form of tabular data and will be implemented by the specialists of the locomotive complex when justifying the efficiency of UzTE16M3 diesel locomotives in real operating conditions.
