Research of Integration and Simulation Technology for Multi-source Heterogeneous Models of Trains

This article introduces the research scheme of multi-source heterogeneous model integration and simulation technology, which integrates and interacts model data composed of multiple software and hardware sources (multi-source) and multiple data types (electrical, control, mechanical, and other heterogeneous data). The application of the combined simulation test of electrical, control and mechanical data of the door system of a Multiple unit is introduced. The integration of multi-source heterogeneous models and the opening of the simulation Technology roadmap can verify the integrity and correctness of the system design by means of digital simulation verification, so as to eliminate potential design errors to the greatest extent, quickly locate faults, improve quality and efficiency, and shorten the actual vehicle commissioning cycle.
