基于车载系统的轨道几何与动力学检测数据集

轨道几何峰值超限及轨道质量指数TQI，包括左高低、右高低、左轨向、右轨向、轨距、水平、三角坑共七项参数。峰值超限为轨道几何局部峰值超过《高速铁路无砟轨道线路维修规则》（TG/GW115-2012）和《高速铁路有砟轨道线路维修规则》（TG/GW116-2013）中规定的Ⅰ、Ⅱ、Ⅲ、Ⅳ级管理标准的参数；轨道质量指数TQI为七项参数在200m区段内标准差的代数和。动力学数据包括脱轨系数、轮重减载率、轮轴横向力、轮轨垂向力、轮轨横向力等参数，在2s时间范围内的最大值。

Track geometry peak over-limit indicators and Track Quality Index (TQI) involve seven parameters: left longitudinal level, right longitudinal level, left alignment, right alignment, track gauge, cross-level, and track twist. The peak over-limit refers to parameters whose local peak values of track geometry exceed the Class I, II, III, IV management standards specified in *Regulations for Maintenance of Ballastless Track Lines for High-Speed Railways (TG/GW115-2012)* and *Regulations for Maintenance of Ballasted Track Lines for High-Speed Railways (TG/GW116-2013)*. The Track Quality Index (TQI) is the algebraic sum of the standard deviations of the seven parameters within a 200-meter track section. The dynamic data includes parameters such as derailment coefficient, wheel load reduction rate, axle lateral force, wheel-rail vertical force, and wheel-rail lateral force, which represent their maximum values within a 2-second time window.
