基于实测数据的地铁车辆动态包络线获取方法研究

Research on Getting Dynamic Envelope Line of Metro Vehicles Based on Measured Data

以北京燕房线全自动地铁车辆为例,基于线路实测数据的动态振动偏移量,利用MATLAB软件编程,通过解析法计算地铁车辆在实际线路上运行的整个过程中车体可能达到的最大包络线。该方法简洁方便,经校核,所计算出来的最大包络线满足限界要求。

Taking full-automatic metro vehicles for Beijing Yanfang Line as an example,based on dynamic vibration offset from measured data of the line,using software programming of MATLAB,the maximum envelope line which the car body can reach in the whole operation process of metro vehicles in actual line is calculated by analytical method.The method is simple and convenient,and the calculated maximum envelope line meets the boundary requirement via verification.
