{"title":"Methodology for assessing the operational efficiency of transport diesel generators","authors":"A. Bogajevskiy, S. Arhun","doi":"10.30977/veit.2022.22.0.4","DOIUrl":"https://doi.org/10.30977/veit.2022.22.0.4","url":null,"abstract":"Problem. Today, there is a problem associated with the need to increase the efficiency of railway transport. Recently developed methods for determining the parameters of energy-saving operational work in stable and transient modes, as well as sets of corresponding technical means from various manufacturers allow us to speak of an integrated energy-saving technology. This development relies on the use of electronic controls. It is very effective both when used on new locomotive diesel generators and when retrofitted during a major overhaul. The integrated indicators existing in railway transport were developed without taking into account the capabilities of modern control systems in the formation of both stable and transient modes. Therefore, it is difficult to obtain estimates on their basis that make it possible to compare the efficiency of energy saving of control systems of various manufacturers and the actual payback period under operating conditions. Goal. The purpose of this work is to develop a methodology for assessing the impact of technical controls on improving the operating efficiency of diesel-generators in a relative form, which allows, even at the stage of preparation for the introduction of energy-saving measures, such as modern frequency and power control systems for a diesel-generator, to determine the efficiency of diesel generators in steady state, transient and idling conditions expected during the operation of the vehicle. Methodology. The paper uses methods based on obtaining relative estimates based on well-known ratios for fuel consumption in stable and transient modes. Results. The simple expressions obtained in the work make it possible to evaluate in a relative form the degree of influence of electronic technical systems on improving the operational efficiency of mainline and shunting diesel locomotives without carrying out a time-consuming and material-resources experimental study. Originality. In the case of a mainline locomotive, the expected efficiency from the use of only frequency and power control systems (electronic regulator) is estimated, and in the case of a shunting locomotive, relative estimates allow us to estimate the expected efficiency from the simultaneous use of two control systems: a start-stop system and an electronic regulator. Practical value. The proposed method of relative estimates can be applied to analyze the potential increase in the operational efficiency of diesel generators of shunting diesel locomotives, the fleet of which is a significant consumer of diesel fuel in railway enterprises, mining and metallurgical industries in almost all countries.","PeriodicalId":153826,"journal":{"name":"Vehicle and electronics.

This article is devoted to the study of the load of the working equipment of the knife pipe boring machine for trenchless laying of linear underground engineering communications by pulling them through the soil. The implementation of this method requires significant traction efforts, which causes big stress in its working equipment. Understanding their meaning is important when designing these machines. Goal. The purpose of the research is to create calculation schemes and mathematical models that will allow you to get an idea of the load on the work equipment and provide it with a qualitative assessment of its stress state. Methodology. In order to achieve the set goal, an idea of the dynamics of work processes of earthmoving and transport machines was put forward. Results. The obtained results made it possible to carry out an analysis of the loads on the working equipment of the pipe dredger, taking into account the processes that occur during the meeting of the knife working body with an obstacle in the process of movement. Namely, it was established that when the back knife of the working equipment meets with obstacles, the stiffness of which increases, from 10.000 to 20,000kN/m, it does not lead to a significant increase in the operating loads, which can be explained by a significant difference in the stiffness of the obstacle and the working equipment. It is possible to reduce the maximum operating loads from 270 to 210kN, or by 27% by reducing the stiffness of the working equipment from 2000 to 500kN/m due to the use of additional elastic nodes or elements that absorb dynamic loads in the metal structure of the knife equipment of the machine. The most significant reduction in operating forces can be achieved by reducing the speed of movement in areas where obstacles are likely to be encountered. The conducted studies showed that changing the movement speed from 1.5 to 0.5 m/s allows to reduce the resulting forces from 330 to 190 kN, or by 43%. Scientific novelty. For the first time, calculation models were obtained for determining the dynamic load of the working equipment of knife pipe boring machines during its collision with obstacles.. Practical value. The results of the research can be recommended for practical use in the design of knife-type pipe deepeners, which are intended for trenchless laying of underground communications.","PeriodicalId":153826,"journal":{"name":"Vehicle and electronics.

An analysis of the literature has shown that some issues of the kinematics and dynamics of the Hooke’s joint are not fully covered. In particular, this applies to the determination of the kinematic characteristics of the relative movements of the links in the movable joints of the crosspieces and cardan yokes, as well as the acceleration of the crosspiece in the study of the hinge. These kinematic characteristics are the basis for dynamic analysis of the cardan transmission; they are used at research of operation of the bearings of a cardan joint cross; they are necessary to determine the energy expended to overcome the forces of friction in these kinematic pairs; they form the basis for evaluating transmission efficiency. Goal. The goal of this work is to determine the kinematic characteristics of the cross in its absolute and relative motions. Methodology. The research is based on the graphical and analytical method of kinematic analysis of spherical motion of a rigid body. At the initial stage, the calculated dependences for determining the angular velocity of the cross in its absolute and relative motions were obtained. The relative angles of rotation of the links in the movable joints of the crosspiece and cardan yokes were determined by integrating the corresponding differential equations. To determine the angular acceleration of the crosspiece, the theorem on the addition of angular accelerations of a rigid body rotating around two non-parallel axes was used. Results. The study of the kinematics of the cardan joint made it possible to identify and eliminate ambiguities in determining the relative angular velocities of the elements of the kinematic pairs of the cross and cardan yokes. Functional dependences for determination of angular acceleration of a crosspiece in absolute and relative movements, and also relative angles of rotation of links in kinematic pairs of a crosspiece and cardan yokes were received. It was shown that the angular acceleration of the crosspiece is a periodic function of the angle of rotation of the input link. During the operation of the hinge, the crosspiece creates insignificant periodic dynamic loads, which should be taken into account in accurate calculations of high-speed cardan transmissions. Practical value. The work is devoted to the study of the kinematics of the asynchronous hinge, which is the foundation for its dynamic analysis and ultimately aimed at improving the output performance of the cardan transmission. The research method combines mathematical calculations with simplicity and clarity of graphic constructions, which contributes to a deeper understanding of the kinematic features of a hinge of uneven angular velocities. The obtained results can be used in the design and study of motor-transmission units, which include the Hooke’s joint.","PeriodicalId":153826,"journal":{"name":"Vehicle and electronics.

Improving the efficiency, quality, reliability and economy of tractor equipment is one of the most important tasks of modern society. This is due to the fact that in agriculture, tractors can perform up to 80% of various operations. The cost of production, product quality, compliance with the conditions of technological operations, etc. depend on the properties and reliability of tractors. The main factor limiting the effective use of tractors in agriculture is the problem of insufficient reliability of tractors, namely, the reliability of its individual components. One of the most important units is its gearbox. The existing methods for diagnosing tractor gearboxes are designed to detect damage, but they are not able to determine the quality of the gearbox at the design and manufacturing stage. Such an opportunity would greatly simplify the process of diagnosing tractor boxes. Goal. The purpose of the research is to assess the quality of design and manufacture of tractor boxes according to their vibration characteristics by identifying design and manufacturing defects, which will allow developing the ways to improve them. Methodology. Methods for detecting statistical data on the boundary values of structural vibrational parameters and their connection with the technical condition of tractors were used. Experimental research methods and mathematical methods for processing and modulating the results obtained were used as well as the methods of statistical calculation and comparison of vibration characteristics with permissible vibrations that do not affect the acceleration of the process of tractor parts wear. Results. Experimental studies of vibro-diagnostic characteristics of tractors were carried out. Studies were made to measure vibration diagnostic indicators; a spectral analysis of gearbox vibration was carried out.
