    Abstract: Working principle of the pneumatic ABS pressure regulators and the role it plays in the car air braking process were described in this paper, so as to elicit the requirements of the parameters in the test of the pneumatic ABS pressure regulators. For the basic parameters, the test method of the dynamic performance was put forward for the pneumatic ABS pressure regulators, and the specific implementation of the testing system was also researched. The authors mainly designed the industrial computer, the drive circuit of the electromagnetic valve, sensors, pressure generation device, data acquisition system, braking system and exhaust system and other units. The whole system was assembled in the laboratory, and the control and test platform were established for it. The experimental results showed that this system has high reliability, accuracy, good stability and low cost. And the precision of measurable pressure was high in the range of 0-12 MPa.
    Key words: pressure regulator; air brake; dynamic performance; test system; reliability
