Abstract: To enable general-purpose commercial multi-body dynamics and finite element software to meet the requirements of simulation and modeling of a high-speed train subsystem, an extensible and flexible framework was set up by utilizing open-source components and the dynamic encapsulating technology. As a case study, a high-speed train pantograph-catenary subsystem simulation platform (TPL. PC) was developed based on this framework. The application result shows that the proposed framework can provide all necessary functions for the high-speed train simulation platform, such as geometric modeling, mesh generation and editing, numerical solution, and 3D real-time visualization. In addition, it can overcome the difficulty of interoperability of geometry models and simulation models in above aspects among different subsystems, which makes the temporal data produced by iterative computation and the result data exchange smoothly
