地铁列车运行加减速度动态采集与特征分析

摘要

Considering that the subway train running progress has fast stop and start, small radius curve, long ramp and etc. Characteristics, it's significant for the train parameter and dynamics characteristic analysis to study the subway train running acceleration and deceleration. The working principle and composition of the acceleration and deceleration dynamic acquisition system based on wireless is described, and the hardware and software processes of acquisition system are analyzed. By measuring the subway train running case of 15 stations, the acceleration and deceleration range, alternating frequency, cycle characteristics and other relevant features are acquired through analyzing. It provides reference for optimizing or adjustding the train running parameters and dynamic characteristcs.%鉴于地铁列车运行具有快启快停、小曲线、大坡道等特点,研究其运行加减速度对分析列车参数及动力学特征有重要意义.介绍了基于无线方式的加减速度动态采集系统工作原理及构成,分析了采集系统的硬件及软件流程.通过实测地铁列车15个车站的运行案例,分析得到加减速度变化范围、交替频次、周期特点等相关特征,为列车运行参数及动力学参数优化调整提供参考.
