DESIGN OF HARDWARE-IN-THE-LOOP TEST BENCH FOR BRAKING AND ANTI-SKID OF TRAINS

To meet the needs of train braking and anti-skid simulation, a hardware-in-the-loop test bed based on the co-simulation model of LabVIEW and AMESim was designed.The hardware of the test bench is mainly composed of an industrial personal computer (IPC), the data acquisition cards and the frame control braking devices (excluding the pneumatic valve unit).IPC provides virtual train vehicle, virtual train running environment, virtual electric brake unit and virtual pneumatic valve unit.In the form of a hardware-in-the-loop test bench, it realizes the functions of train traction, braking and anti-skid.Finally, according to the requirements of standard EN 15595, the validation of the test-bed is verified by comparing the actual line data with the simulation data.
