    Determination of Basic Data for the Six-Polar Model of Electrical Tonal Rail Circuit
    (Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, 2016) Romantsev, Ivan O.
    EN: Purpose. Development of the model and input data of the six-polar model of electrical tonal rail circuit as an example of the functional units with concentrated parameters. Methodology. For the development of the six-polar model is necessary to form the structure of the object of study, taking into account all the ground resistances of each functional block of electrical tonal rail circuit; form a six-polar model and define the parameters of the rail track filter. Findings. The data make it possible to form a full six-polar model of electrical tonal rail circuit and obtain the necessary dependencies between electrical parameters and current performance of electrical rail circuit. Originality. During the work formed the structure of the six-polar model of electrical tonal rail circuit, method for determining the mathematical model of the six-polar element of electrical tonal rail circuit with concentrated parameters. Practical value. The obtained data will allow optimizing the maintenance costs of the electrical rail circuit and cable network parameters. Further analysis of dependencies will determine the optimal permissible limits of controlled parameters for diagnostics system of railway automation devices.

    Modeling of Rectangular Pulse Oscillator of Electrical Tonal Rail Circuit
    (Dnipropetrovsk National University of Railway Transport Named After Academician V. Lazaryan, Dnipropetrovsk, 2016) Romantsev, Ivan O.; Taynolyub, Mykola S.
    EN: circuit it is necessary to determine the rectangular-pulse oscillator circuit based on integrated circuits, perform the analysis, mathematical and physical modelling, to define the parameters of each output signal. Findings. The obtained data allow to form a stationary circuit of rectangular signals oscillator of electrical tonal rail circuit excluding the output frequency and power tuning. Originality. During the work performed the simulation of amplitude-manipulated signal oscillator of electrical tonal rail circuit based on logic elements. Practical value. The data obtained allow to optimize the costs of production of tonal rail circuits equipment.
