Abstract
With the development of heavy-duty trains in the direction of heavier loads and a more extended number of groups, the longitudinal impact force has become the reason that restricts its development, and it will also affect the safety of train operation. Researchers proposed Electronically Controlled Pneumatic (ECP) and Segmented Electro-Pneumatic (SEP) braking systems to reduce the longitudinal impact force, but their differences are not apparent. In this paper, based on SIMPACK, AMESim and Simulink, the train dynamics model, pneumatic braking model and braking control module are established, and a comprehensive computing model is constructed, which analyzes the braking performance of ECP and SEP. The results show no significant difference in performance indicators such as braking distance and brake cylinder pressure between ECP and SEP braking. In addition, the differences in the working mechanism of ECP braking and SEP braking are discussed in detail, which will provide a reference for optimizing the electronically controlled braking system.
