Yeritsyan B. Body tilt combined system synthesis of hig-speed electric rolling stock

The object of research - the processes accompanying train movement in curved sections of the path and the process of energy conversion in the electromechanical and pneumatic drive units combined tilting of the body. The aim of research to synthesize body tilt speed electric rolling stock of the combined system consisting of electrical and pneumatic units and enables the use of a 1520 mm gauge railways. Methods of research: method of least squares and Chebyshev polynomials on the set of equidistant points to approximate the results of numerical experiments for entering into curved sections and the calculation of the magnetic field of the linear motor, methods of genetic algorithm and Nelder-Mead in determining the optimum parameters of the linear motor tilting of the body drive, the finite element method in the calculation of the magnetic field of the linear motor, half of the segment division method for solving the optimization problem in the determination of the necessary angle of inclination of the body high-speed train, simulation techniques for modeling dynamic processes of the combined tilting of the body drive. Theoretical and practical results: developed a mathematical model and simulation of the pneumatic actuator combined tilting of the body, subsystem simulation management system model combined drive tilting high-speed train, method of identifying the parameters of the linear motor. Propose to tilt the body to apply a combined system consisting of a linear motor and an adjustable air suspension of the second stage; to set optimum values geometrical relations of linear motors, which may be used in combined tilting of the body system, to identify the main of energy indices depending tilt drive. Scientific novelty: for the first time developed a method of determining the optimum angle of inclination; first, through the optimum design for the defined geometric relationships of linear motors that ensure the opportunity for of a body inclination angle from the maximum 1° to 7°; for the first time developed by simulation model of the processes of electromechanical energy conversion in the body tilt system; for the first time determined dynamic indices of the proposed components of the mechanism. The realization degree: the results obtained in the dissertation work utilized establishments PJSC "Ukrainian Railway" Kharkov branch department DP "PVIZTRU" "Ukrzaliznychproekt" (Kharkov), "Service locomotive farms" regional branch "South railway" PJSC "Ukrainian Railway" (Kharkov) and the learning process of faculty "Electrical transport and diesel locomotive engineering" NTU "KhPI" in the preparation of laboratory practical and methodical support. The branches of this production enterprises of transport engineering industry, enterprise electrical engineering field, Research Studies Institutes and a training process.
