Abstract: The three-dimensional dynamic simulation model based on varying parameters is
established for the CRH high-speed train, and the real-time transfer and assembly of various train
element models during the process of motion are achieved. A high-speed train movement
simulation system is developed using Visual C++ 6.0, OpenGL 3D graphics library and the Oracle
Database. A comprehensive integrated simulation system between High-speed train movement
and three-dimensional line design is established. The experiments show that good simulation
results are obtained.

Key words: high-speed train, three-dimensional modeling, motion simulation, simulation
