摘　　要：搭建高速列车牵引计算多质点均质棒模型,实现列车的自动连续计算。为了将高速列车牵引计算与三维视景结合,基于高层体系架构平台和用户数据包协议,开发了三维视景驱动程序;针对HLA平台、视景驱动程序、三维视景三者之间列车位置信息的传输问题,设计了一种对列车位置信息进行转换的算法,有效解决了视景前推问题,以及列车运行距离和区段偏移的显示问题;分析RTI的时间推进方式,采取增加视景驱动程序仿真时间的方法,实现三维视景实时推进功能。测试结果表明,视景能正确接收到列车速度、位置信息,实现了高速列车牵引运行的可视化仿真。This paper has built the multi-particle homogeneous rod model of high-speed train,which realizes the automatic and continuous calculation of a train.In order to combine high-speed train traction calculation with three-dimensional view,based on High Level Architecture（HLA） and User Datagram Protocol（UDP）,the three-dimensional driving program is developed.Aiming at the data transmission among HLA platform,the threedimensional view driving program and three-dimensional view,this paper designs a kind of algorithm that transforms the train position information,which solves the problem of the three-dimensional view moving and the display of the train running distance and segment offset.On the basis of analysis of the way of RTI＇s time advance,this paper uses the plan that increases the simulation time to realize the real-time moving of the three-dimensional view.The test result shows that the three-dimensional view can receive the train speed,position information correctly.The visual simulation of the high-speed train running is realized.
