摘　　要：本文以地铁运行线路为基础设计城轨三维电子沙盘模型,同时利用OSG(OpenSceneGraph)技术驱动电子沙盘中地铁的运行。从场景模型的生成、沙盘中动态场景的控制、列车在三维空间的定位算法等方面研究虚拟仿真技术在城轨列车运行系统中的运用,可以为列车运行系统的设计提供参考和验证。Three-dimensional electronic sand table for Urban Transit was designed based on lines of subway.OSG technology was used to simulate functions of the trains in three-dimensional electronic sand table.The paper studied on the application of virtual simulation technology in train operation for Urban Transit from the establishment of model environment,the control of dynamic scene,the positioning algorithm of trains in threedimensional electronic sand table.The most special importance was that it could provide reference resource and feasible verification for the design of Train Operation System for Urban Transit.
