摘　　要：为保证汽车制动稳定性,减小或消除前后制动器制动的时间差,合理布置气制动系统的制动管路和优选制动系统的相关部件及总成非常重要.为此,研制了由微机控制的气制动系统检测台架试验台;该试验台由压力传感器、信号放大器、数据采集系统、计算机、气压源等组成,可以模拟测试汽车的气制动系统的制动及解除制动的反应时间;应用该试验台对某大型客车气制动系统进行了实测,证明系统实用可靠,与路试相比可节约大量的试验经费和试验时间.The stability of the brake system is a key factor for the vehicle safety. It is important for the air braking system＇ s stability to shorten the time lag between the front brake and the rear brake, the reasonable disposal of the air pipeline and the optimization of the braking system design. A test bench is developed to test the performance of the air braking system, which is mainly made of pressure sensors, signal air resource and so on. Based on this test bench, the reaction amplifiers, data acquisition system, computer, pressing time of the system while braking and abandoning brake can be measured. Using this test bench, the performances of the air braking system of a certain commercial vehicle is detected. Compared with the actual road test, it can save the cost and the time for experiment largely.
