Electro-pneumatic braking system (epbs) components can be frequently used in anyrncommercial automobile vehicles regardless of their size of outputs. Their difference is in thernamount of longitudinal force developed inside these components according to the size of thernautomobile. The simulation of electro-pneumatic brake systems has of great importance inrnorder to understand the fluid dynamics inside these brake components.rnThe electro pneumatic braking system is applicable in any automobiles. But this particularrnsystem is applicable in a train vehicle (coach). This paper presents a computational modelrnbased simulation of electro-pneumatic braking system used for prediction of fluid dynamicrnbehavior inside the systems and to compare the simulated results with the pneumatic one.rnThe system is modeled and simulated in modeling and simulation environment calledrnMATLAB SIMULINK. Considering the complexity of the electro pneumatic braking systemrncomponents and the related phenomena of fluid motion inside these components, specialrnmodels have been elaborated using flow chart algorithm.rnThe simulation result shows good agreement with measurement data found from differentrnliterature reviews but have a big difference in time response with the pneumatic brakingrnsystem. The comparative measurement data (experimental data) found from differentrnliterature reviews and simulation result found from this simulation study confirms that thernsystem is modeled correctly and this simulating tool can be effectively used in design,rnresearch and development of electro pneumatic braking systems.
