Shevchuk Y. Methods and means of tram electromechanics brake automated control.

Object of the research - the process of the technical state determining of trams electromechanical braking systems basic units; the purpose of thesis is to increase the probability of trams electromechanical braking system parameters control by improving control systems of its elements; used methods numerical methods; mathematical modeling methods; theory of finite automata; algebra of logic; probability theory and fuzzy sets; genetic algorithms; analytical capabilities of computer algebra systems; methods of mathematical statistics; theoretical results, which is based on the detected analytical dependence between the parameters of tram electrical and mechanical braking phases, which allowed us to estimate the efficiency of the electromechanical brake system; The method of condition monitoring multisection rheostat received further development, by taking into account the identified parameters depending on the electric power circles and combination of closed and open-loop contacts, unlike the known can more adequately determine its technical condition. A mathematical model of trams electric traction motion, allowing improved tram slip evaluation method, which unlike the known into account the actual braking force at the junction of rail-wheel defined by the variables of the power circle. Practical results - the algorithm setting uniform braking force along the axes wheelsets, the implementation of which allows them to provide the same speed when braking the tram. Based on the developed methods proposed device detection and control the value of the mechanical torque electromechanical brake that will provide information about its condition. A computer model of the mechanical braking torque determination in an environment Matlab Simulink, which allows you to quickly debug to work with various input parameters and to investigate its performance in different modes. A block diagram of the algorithm and system identification and control of tram electromechanical brake mechanical braking torque in microprocessor performance that can improve functionality and flexibility of the proposed adjustment. Degree of introducing - the results of work in communal introdused the enterprise "Vinnitsa tram and trolleybus management" and in the academy process Vinnytsia National Technical University. Scope (area) uses of - enterprise, using electrical train.
