Yakunin D. Electromechanical system of a drive with the linear engine for an inclination of bodies of a high-speed rolling stock

Object of research: process of electromechanical transformation of energy in system of an inclination of a body of a rolling stock. A research objective: working out of scientific bases of creation of the electromechanical system providing a direct drive with the linear engine of the mechanism of an inclination of bodies of a high-speed train and an estimation of influence of such system on operational properties of these trains. Methods of researches: imitating modeling of processes in electromechanical system of an inclination of a body; digital modeling of processes in system "wheel-rail"; a method of eventual elements - for calculation of a magnetic field of the converter of energy; methods of approach of function - for approximation of the data of digital modeling; for acknowledgement of reliability of model - physical modeling. Theoretical and practical results: a scientific substantiation of possibility of application of the linear engine as a power drive of the mechanism of an inclination of bodies of a rolling stock. Creation of recommendations for choice of parameters of the linear engine and the energy converter. Creation of universal imitating model of work of mechanisms with linear electromechanical converters of energy. Improvement of mathematical model of processes in system "wheel-rail". Definition of the loading characteristic of mechanisms of an inclination of bodies. Working out of configuration of perspective crew with the body inclined by means of the offered drive. Practical value is confirmed by introduction of dissertational work in OAO HK "Luganskteplovoz". Novelty: for the first time the system of an inclination of a body on the basis of the coaxial linear engine of a direct current of electromagnetic type of an armored design of the cylindrical form and the semi-conductor converter of energy go-straight type is offered; For the first time the mathematical and imitating model of transformation of energy in system of an inclination of bodies with use of packages Matlab and definition of parameters of the linear engine by the calculations of a magnetic field approximated by polynoms of Chebyshev on set of equidistant points is developed; a number of laws of influence of geometrical parameters of the kinematic scheme, geometrical and electromagnetic parameters of the linear engine on power and power characteristics of elements of system of electromechanical transformation of energy is established; criteria of capital and operational expenses for an estimation of an overall performance of the linear engine are offered. For a test problem optimum value of diameter of an anchor and quantity of coils is established; it is established that the body inclination in a curve does not render considerable influence on deterioration of wheels. Introduction degree. Scientific results of work are introduced on OAO HK "Luganskteplovoz" in the course of designing of a perspective rail rolling stock. Practical value is confirmed by introduction of dissertational work in OAO HK "Luganskteplovoz". Application sphere - electrotransport.
