Makarenko Y. Improvement a pneumatic spring suspension trains by applying the regulator of body position on the basis of mechatronics

Object of research: the dynamic processes involved in the interaction of the rail track and the electric train with air-spring suspension. The purpose of the study: to solve scientific and practical problem of improving the pneumatic spring suspension of the train by applying the provisions of mechatronic controller body with appropriate software. Research methods: digital simulation; theory of mathematical planning of the experiment; methods of experimental research. Theoretical and practical results: designed and mechatronic regulator body position based on microprocessor technology that stabilizes system performance pneumatic spring suspension in the operation and changing environmental conditions; a program of microcontroller mechatronic regulator body position, which provides the ability to get rid of self-oscillation phenomena in the pneumatic spring suspension system electric train; recommendations on the choice of rational parameters of regulators body position; created a simulation model that can detect conditions of emergence and development of oscillatory processes and methods for their exclusion at the design stage electric train. Novelty: first obtained patterns of the pneumatic spring suspension system in the presence of impulsive disturbances of mechatronic controller position of a body in conjunction with periodic perturbations of the track; first defined depending on the dynamic qualities of electric pulse duty cycle controlling disturbances coming from the mechatronic regulator body position; The regularities of the influence of parameters of the regulator body position (dead zone inductive sensor, the range of variation of the input voltage of the microcontroller, the characteristics of three-stage cycle of work, number of measurements of body height per cycle, appropriate electronic components) that provide the quality of regulation. Degree of implementation: results of the thesis is embedded in the practice of engineering rolling stock at JSC "Kriukov car building works". Scope of use: electric transport.
