Train pneumatic brakes are part of a train safety system; and are thus critical components. This paper illustrates how modeling can be applied to efficiently design such system; from requirement definition to HIL testing. The valves modeling is discussed along with the system level model. Moreover; in order to study the wheel-slide protection device; a model of the wheel-rail interface has been developed.
The contact model; written in Modelica; has been validated against measurement for different conditions of contact (dry; wet…). The model is fully parametric and allows testing of various adherences.
Finally; the resulting system composed of pneumatic valves; wheel-rail interface and rolling-stock is exported through c-code for integration into a HIL system; providing an efficient test platform for the electronic Brake Control Unit.
