高速铁路牵引计算与仿真系统研究

高速铁路的牵引计算与仿真对优化高速铁路线路设计、优化列车运行时间等方面具有重要意义。然而由于缺少高速铁路牵引计算规范和动车组数据资料保密未公开等原因,导致对高速铁路牵引计算仿真与系统的研究较少。采用动车组特性曲线CAD矢量化法和程序开发相结合,解决了高速铁路牵引计算力学数据的有效获取。基于多质点模型,建立了动车组牵引力、制动力、列车阻力的计算方法和公式。从牵引、惰行和制动三方面建立了动车组运动模型求解和运行过程计算算法。在此基础上,采用C#2010编程语言和Access数据库,开发了基于多质点模型的动车组牵引计算与仿真系统。实现了动车组数据和线路等数据的一体化管理;采用动车组编组等参数化设置,实现了不同参数下的高速铁路牵引计算与运行过程的完整仿真。

Research on Traction Calculation and Simulation System of High-speed Railway

The traction calculation and simulation of high-speed railway has great significance for optimizing the design of high-speed railway lines and optimizing train running time. However,due to the lack of high-speed railway traction calculation specifications and the confidentiality of EMU data,the research on traction calculation,simulation and the system of high-speed railway is insufficient. This paper combines the vectorized EMU characteristic curves with the program development to accomplish effective acquisition of high-speed railway traction calculation mechanics data. Based on the multi-mass model,the calculation method and formula of EMU traction force, braking force and train resistance are obtained. From the aspects of traction,idle behavior and braking,the solution of EMU motion model and the running processcalculation algorithm are established. On this basis, the multi-mass-model-based EMU traction calculation and simulation system is developed by means of C# 2010 and Access database. The integrated management of data and lines of EMU is realized. Using parameterized settings such as EMU grouping,the complete simulation of high-speed railway traction calculation and integrated operation process under different parameters is implemented.
