Real-time Simulation of Locomotive-Track Coupled Dynamics

Locomotive-track coupled system is a complicated system, not only in dynamics, but also in geometrical structure. In this paper, on the basis of the complexity analysis of the present vehicle-track coupled dynamics simulation, from the view of computer simulation structure and system integration, we study several integrated and real-time simulation method considering digital computation and visualization, and explore applications of multi-thread, DDE, distributed simulation technology and computer network in locomotive-track coupled dynamics. It shows that these methods are feasible, especial the DCOM-based simulation and the one based on off line computation data files share.
