Research on Train Running Line Simulation System

介绍了列车运行线路仿真系统整体功能和结构,阐述了整个仿真系统的仿真原理和方法,如列车运行过程中牵引力,制动力,列车运行阻力的运算仿真和线路图像与实物视景的仿真。详细阐述了列车运行仿真过程中对列车运行微分方程的简化处理办法、以及线路坡道运行仿真中寻找变坡点的方法,并重点介绍了采用当前最新的多媒体技术来实现视景仿真过程线路图像同步的控制方法,以及在列车低速运行时以插帧的方法实现平滑调速的技术。

The paper introduces the whole function and architecture emulate system and describes emulation theory and technique of the whole emulate system, for instance, the traction force, the brake power, the operation emulation of running resistance and the emulation of route graph and material object landscape. It is also represented in detail the simplified process for differential equation of train running in the emulation process while train is in motion, and the way of seeking changeable slope point in the route ramp process emulation. Moreover, it also focuses on presenting the control method adapted the latest multimedia techniques to realize the synchronism of route image in visual landscape emulate process; the technology that realizes smooth-speeded change by inserting frame when the train is in motion slowly.
