In order to improve the efficiency of the design and verification of antiskid system, a simulation test method of antiskid system by using the hardware-in-the-oop simulation technology was proposed. The working principle of antiskid system was introduced, and the air control unit model, vehicle dynamics model and wheel rail adhesion model for antiskid system test were established. Hardware-in-the-loop simulation test platform for antiskid system was set up, and a simulation test for EMUs antiskid system was carried out. The results were compared with the test results. The test result proved the test validity of antiskid system hardware-in-the-loop simulation test platform, the evaluation indexes of effectiveness validation for test platform satisfied the requirements of industry standards.
