| dc.description.abstract | Triple valve malfunction (triple valve defect) causes an effect on braking distance, braking time and braking force. [10]. From those defects leakage through triple valve piston, sliding valve and graduating valve are taken for analyzing the effects of malfunctioning of locomotive triple valve on braking time. The defects during leakages through triple valve piston head, triple valve piston rod, sliding valve and graduating valve causes air pressure to decreases lower than air pressure during normal operation of triple valve. Maximum and minimum pressure losses during leakages through triple valve piston head, triple valve piston rod, sliding valve and graduating valve are taken for Analyzing braking distance, braking time and braking time. The mathematical modeling during pressure losses through those triple valve components are used for modeling block diagram by Simulink matlab during leakages through triple valve piston head, triple valve piston rod, sliding valve and graduating valve. The simulation is modeled by using Simulink matlab. The simulation result shows triple valve with maximum and minimum % of leakages increases braking time and braking distances, but decreases braking forces | en_US |
