摘要轨道不平顺不同波长成分对列车运行平稳性、舒适性影响程度不同。为了更有效判别轨道的潜在病害，提出一种基于带通滤波的轨道不平顺敏感波长计权评价指标，即轨道加权质量指数（F-TWQI）。基于车辆-轨道耦合系统动力响应分析确定敏感波长权重曲线，按1/3倍频程对轨道不平顺进行频域划分并设计相应的带通滤波器，对每个频带的轨道不平顺波形分量的标准差赋权，求和得F-TWQI。以轨检车实测高低不平顺数据为例，对比分析TQI、基于EMD的轨道加权质量指数E-TWQI和F-TWQI与UIC513的相关系数。结果表明：三者相关系数分别处于0.6~0.7、0.7~0.75、0.8~0.85，对敏感波长计权更能反映轨道实际状态；F-TWQI能避免E-TWQI端点效应的局限性，计算效率得到极大地提升，为快速、准确分析铁路工务的潜在安全隐患提供了一种新的方法。

Abstract：Different wavelength components of track irregularity have different effects on train running smoothness and comfort. Here, in order to more effectively identify potential diseases of track, a weighted evaluation index for sensitive wavelength of track irregularity based on band pass filtering was proposed, i.e., the track weighted quality index (F-TWQI). The weight curve of sensitive wavelength was determined based on dynamic response analysis of vehicle-track coupled systems. Then track irregularity was divided in frequency domain with 1/3 octave and the corresponding band-pass filters were designed. Standard deviations of track irregularity wave components within each frequency band were weighted and summed to obtain F-TWQI. Taking the data measured with an inspection vehicle for track vertical profile irregularity as an example, three correlation coefficients between TQI and UIC513, E-TWQI obtained based on EMD and UIC513, F-TWQI and UIC513, respectively were compared and analyzed. The results showed that three correlation coefficients are in ranges of 0.60-0.70, 0.70-0.75 and 0.80-0.85, respectively; sensitive wavelengths being weighted can better reflect track actual state; F-TWQI can avoid limitations of E-TWQI’s endpoint effect to greatly improve computational efficiency, and provide a new method for quickly and accurately analyzing hidden dangers of safety in railway engineering.

Key words： track irregularity sensitive wavelength band-pass filter track weighted quality index
