Gorbunov N. Theory and practical realization of the system approach in the construction of the carriage of locomotive

The dissertation is devoted to the problem of the development of theo-retical fundamentals for the construction of the carriage of locomotive on the base of system approach, using the theory of decision making, the methodology of experi-mental -theoretical researches, the search and ground of project constructions, their laboratory, stand and operating tests. New solutions of a complex problem of im-proving locomotive traction and dynamic characteristics, qualities have been re-ceived; the ways of improvement of mechanical units in the system of carriage of locomotive are scientifically substantiated. The conceptual model of scientific researches in creation of highly effec-tive facilities of rail transport and choice from a great number of perspective struc-tural decisions is improved. Scientific-practical results of the work are the base for the solution of the problem to provide quickly highly effective railway machinery in Ukraine. Keywords: system approach, imitation modeling, contact, adhesive force, wheel pair, profile of wheel and rail, friction state, stand equipment, information- measuring complex, mechanical trajectory, locomotive, hauling drive.
