The safety of articulated vehicle is crucial to transport efficiency. To improve the efficiency of braking performance and detection, and offer a qualitative analysis, this study focuses on the characteristic relation between static and dynamic braking performance of the articulated vehicle. In this paper, the brake chamber pressure increases to 10 % of the maximum working pressure and 480 kPa as a node. The effective pressure growth rate of the brake chamber is considered as the major index of air brake system delay. The pressure limit of air dryer and the effective section cross-sectional of the brake chamber is determined by the real vehicle test, and the influence of air brake system delay on static and dynamic braking performance is analyzed, so as to find out the correlation between effective pressure growth rate and static and dynamic braking performance. Based on a large number of experimental data, the correlation model between the braking distance and the effective pressure growth rate of the emergency braking is obtained at the initial speed of 30 km/h, and the rationality of the adjusted model of vehicle test results is verified. It can be concluded that the effective pressure growth rate is the main indexes for braking performance adjustment and tests of articulated vehicle.
