摘要：
To accurately acquire the dynamic characteristics of pressure response of commercial vehicle pneumatic braking system, a pressure response model is constructed and verified. The influences of the coupling relationship between the brake pipelines and various components are considered. According to the working mechanism of various components in the braking system and their connection with the pipeline, the theoretical model of pressure response including pneumatic pipeline, air storage tank, brake air chamber, relay valve and other components is established. The distributed parameter model of the pneumatic pipeline is solved by adopting cubic interpolated profile method, thereby the simulation model of each key component is constructed, encapsulated and added to Simulink simulation model library. Taking a dual circuit pneumatic braking system in a commercial vehicle as an example, the pressure response simulation model of the whole vehicle pneumatic braking system is established. The experimental simulation results are compared with the test data from a test bench of real vehicle. It is found that the maximum root mean square deviation of each pressure measurement point is only 10 kPa, and the correlation coefficient reaches 0.98. Taking the front axle brake chamber as an example, the influences of cases with/without pipeline on pressure response are compared, and the necessity of considering pipeline is verified. This pressure response model of the pneumatic braking system provides a reference for performance analysis, structural design and optimization of pneumatic braking system of commercial vehicle, as well as for braking control development. © 2020, Editorial Office of Journal of Xi'an Jiaotong University.
