Buriakovskiy S. The scientific bases for the selection of electric drives of turnouts for rapid and high-speed railways

3. Object of research - systems of electromechanical transformation of energy of electric drives of switching transfers. The purpose of the research is to create a scientific basis for the choice of electric drives for switching transfers on the basis of modern and advanced electromechanical systems for high-speed and high-speed railway electric transport systems. Methods of research - methods of the generalized theory of electromechanical energy converters; Methods of the theory of automatic control; The Sieger-Nichols method and the methods of fuzzy logic; Simulation simulation; Methods of physical modeling. Theoretical and practical results are the possibility of using scientific provisions for the development of design developments and technological processes for the creation of perspective switch translations; Acquisition of technological experience in the creation of a physical model of the electric drive of the switching of the coupler type with the gate-induction motor and microprocessor-based control on the basis of phase-logic; The universality of the received scientific positions. Novelty - for the high-speed and high-speed electrified the further development of the theory of electromechanical energy conversion in the part of the choice of the type of electric drive switching, which, unlike the existing, from the common positions and general criteria takes into account the characteristics of the performance characteristics and the influence on them of the geometrical and electrophysical parameters of various types of engines And makes it possible to compare them, which allows us to determine the tendency for a transition from motors of the rotary type - direct current, asynchronous and valve-and Nuclear to linear - electromagnetic type and inductive with microprocessor control systems; Further developed the theory of simulation of electromechanical systems of directional translations in the direction of creating a generalized mathematical model of work processes taking into account the features of the electric motors involved in them; The generalized vector criterion is proposed for the first time in order to evaluate the efficiency of the operation of switching transmissions; according to the module of this criterion, the final estimation of the efficiency of the use of a specific type of the electric drive of the switch transfer is carried out; For the first time, according to the vector efficiency criterion, rational areas of use of different types of electric drives are proposed: drives on the basis of the DC motor and the asynchronous motor - for modernization of street transfers of trunk transport, spool drives on the basis of the gate-induction and linear motors - for the wanderers of the switching of high-speed and high-speed motion , Drives on the basis of a linear engine of an electromagnetic type - both for moving the twists and moving core of the crosswind Transfer The degree of implementation - the results of the dissertation work are introduced in the State Enterprise "Design and survey institute" Ukrzaliznichproekt "of railway transport of Ukraine" (Kharkiv), PrAT ELAKS (Kharkiv), in the educational process at the Institute of retraining and professional development of the personnel of the Ukrainian State University of Railway Transport (Kharkiv) and NTU "KhPI". Scope of use - in the field of high-speed rail transport and general-purpose electric drives.
