摘要
简述了列车交会动态压力波实车实验测试系统的组成和基本原理。系统以压阻式压力传感器、数据采集仪和微机为核心，应用超声、红外检测技术，实现了列车交会压力波、交会车辆侧壁间距及相对车速的同时测量，并成功应用于广深线实车实验中。
The principles and construction of a pressure wave measuring system for passing trains are presented.The system is mainly composed of piezoresistive sensors,data sampling instruments,infrared detectors,supersonic distance detector and PC.The pressure wave,the distance of the passing trains side wall,the relative velocity when train is passing by another are recorded simultaneously.The system was used in the experiment on Guangsheng Quasi high Railway successfully,the results well matched with what the references presented.Other problems existing in train experiment are also discussed.
