轨道交通车辆运行平稳性评估算法的实现

摘要

Smooth performance of railway vehicles is key factor which affects riding comfort and completeness of goods.In this pa-per,the standard of GB5599-85 is analyzed and the evaluation algorithmic of smooth performance for railway vehicle is realized. With MATLAB7.0 as a platform,the mean value method is applied to amend the test data with linear section.The low pass filter is designed using the work-box FDA of MATLAB.The evaluation algorithmic of smooth performance for railway vehicles is de-signed according to standard requirement.Smooth performance of metro is estimated using this algorithmic.The experimental re-sults show that this method meets the engineering requirements.%车辆运行平稳性指标是直接影响乘客乘坐舒适性以及货物的完整性的关键因素。对GB5599－85标准进行分析，实现了对车辆运行平稳性指标的评估。以MATLAB7．0为平台，运用均值法修正直线区段的试验数据，并利用MAT-LAB工具箱FDA设计出低通滤波器。按照标准要求，设计出车辆运行平稳性评估算法。运用该算法对地铁车辆平稳性指标进行评估，试验结果表明该算法是可行的。
