城轨列车特性曲线计算系统的实现及应用

Application of Characteristic Curve Calculation on Urban Rail Train

分析了城市轨道交通列车的牵引和制动特性。依托经验公式建立了城市轨道交通列车牵引计算与仿真的单质点模型。介绍了以MATLAB编程技术为基础,综合数值分析、数据处理等相关技术开发的城市轨道交通列车特性曲线计算系统的功能结构及主要模块的算法,并以实例来验证系统的可行性和实用性。

This paper put forwards the traction and brake characteristic figures,outlines the mathematical model for traction and brake calculation of urban rail train operation.Based on some experiential formulas,a single-particle simulation model was built up.Then based on numeric analysis and data manipulation technology,this paper develops the simulation system through MATLAB,which considers fully the needs of users and the characteristic of train operation.An example is raised to verify the feasibility and practicality of this calculation system.
