Abstract: A comprehensive performance test system of the automobile air pressure control valve is designed according to the automobile industry standards. The design of a test pipe for 2 air supply circuits, 3 air pressure control circuits and 5 venting and loading circuits can meet the air circuit control requirements for performance test of air pressure control valve of brake system of commercial vehicles. The design of straight-line and rotating loading mechanism driven by servo motor can meet the loading requirements for static characteristic test of main brake valve and hand operated valve. The design of dynamic-characteristic loading mechanism below low-friction air cylinder can meet the loading requirements of dynamic characteristic test of air pressure control valve, the design of data acquisition control system based on Yanhua PCI1716 can meet the data acquisition control requirements of 3 circuits of analog quantity output, 40 circuits of digital quantity output and 12 circuits of analog quantity input. By testing the test system, the test data shows that the sealing of this system is less than 0.6 kPa in 600 s and the standard deviation is less than 0.07 kPa. The mean cut-out pressure of the dryer is 745.16 kPa. The mean reseating pressure is 620.25 kPa. The mean backflow pressure is 59.40 kPa and the standard deviation is less than 1.7 kPa. The standard deviation of the opening pressure, protection pressure and closing pressure of the four-circuit protection valve is all less than 2 kPa. The dynamic characteristic response time of the air pressure control valve is less than 0.4 s, the release time is less than 0.6 s and the standard deviation is less than 5 ms. Test results show that the system render stable test data and meets the test requirements.
