Abstract:  This thesis designs an emulation test bench of CRH380B EMU brake system based on virtual instrument. Taking physical brake controller in end car as research object, computer simulation and emulation is used to realize the functions of periphery network environment, electrical control and pneumatic system, and finally completes the establishment and commissioning of semi-physical emulation test bench. The test result shows that brake compliance is corresponded basically to test data of the train.

Key words:  CRH380B EMU, brake system, virtual instrument, MVB communication, simulation analysis
