Krasyuk A. Improvement of pneutronic braking system of vehicles

Object of study - work process circuit of the pneutronic braking system with function and ABS. Subject of research - the influence of the construction of the proportional modulator and its control system them on transient processes in circuit of the pneutronic braking system. We used the analytic method of mathematical modeling and numerical methods for solving differential equations. Confirmation of theoretical concepts was carried out by experimental studies in conditions stand. Scientific novelty lies in the fact that the first set of dependence, which can justify the design parameters of the proportional modulator driven by a stepper motor. A concept which has developed the idea of a systematic approach to designing control systems of pneutronic braking system. The practical significance of the study is that the developed by addiction, which allows to determine the initial parameters of the electro-pneumatic brake actuator with proportional modulator and to model its transients, the concept of system design, control systems of pneutronic braking system. Adopted for use at JSC "Volchanskiy aggregate plant", OJSC "Poltava Automobile Units Plant" and NPP "Elon-TT" technique used in the design pnevoaparativ. The practical use of the results aimed at achieving social effect and improve the working conditions of drivers, reducing the number of accidents and improve active safety of vehicles in general. Scope: enterprises that design and manufacture of braking systems for vehicles and units to them.
