【Abstract】 This paper shows a modular model library about jointless track circuit, based on software Simulink in Matlab. The mathematical models of some main components are described, for example, electrical sectionalizing joint and transformer. It also discusses the approach of model encapsulation and graphic modeling. These models together with the graphical model builder have been applied to simulate a jointless track circuit with S-shaped electrical sectionalizing joint to assess the ability of the model. The presentation of model library can not only help readers to have a good ideal of inner principle of track circuit, but also provide good reference evidence for design the structure of it.更多还原
