Agricultural tractors are equipped with air braking systems to control and operate the braking systems of towed agricultural vehicles. This paper presents a mathematical model of a hydraulically actuated trailer brake control valve. The results of the statistical Kolmogorov-Smirnov test confirmed the consistence between the experimental and simulated pressure transients during testing the response time of a farm tractor's control circuit. The computer model developed in Matlab-Simulink can be used as a tool to analyze transient processes by using simulation methods in the process of designing the air braking systems of farm tractors.

Ciągniki rolnicze są wyposażone w powietrzne instalacje hamulcowe do sterowania i napędu układów hamulcowych pojazdów ciągnionych. W niniejszej pracy przedstawiono model matematyczny uruchamianego hydraulicznie zaworu sterującego hamulcami przyczepy. Wyniki testu statystycznego Kołmogorowa-Smirnowa oceny zgodności doświadczalnych i symulowanych przebiegów czasowych ciśnienia podczas badania czasu reakcji obwodu sterującego ciągnika Pronar 1531A potwierdziły adekwatność opracowanego w Matlabie-Simulinku modelu komputerowego. Model komputerowy może być wykorzystany jako podsystem do analizy metodami symulacyjnymi procesów przejściowych w procesie projektowania powietrznych układów hamulcowych ciągników rolniczych.
