单列高速列车运行仿真模型与算法
Simulation Model and Algorithm for Single High-Speed Train Operation
摘要
Abstract
The line model with three-layer node network is built based on the line characteristics of highspeed railway. The top layer describes stations and sections. The middle layer describes station center-lines, the dividing points between stations and sections, the change point for the speed limit of lines, and the lines connecting these points. The bottom layer describes the change points of the actual line attribute and the lines between them. Considering the scattered driving force and evenly distributed mass of highspeed Electric Multiple Unit (EMU), EMU is regarded as the chord body with such attributes and the chord body model of EMU is established. The stress state of EMU is analyzed in the points of gradient change and curve change, and the corresponding train acceleration formula is derived. A simulation algorithm of high-speed train operation based on pre-deduction is proposed. The simulation system for single high-speed train operation is developed by integrating the three-layer node network, cord body model and pre-deduction simulation algorithm. The example simulation has verified the accuracy and practicality of simulation model and algorithm.关键词
