摘要
为实现高速磁浮线路不平顺准确预测，结合高速磁浮线路结构组成和技术特点，提出一种基于正态分布叠加原理的高速磁浮线路不平顺拟合方法。以线路轨道特征长度(,l,=l 032 mm)为基准，分析特征长度,l,、导向基础长度3,l,以及桥梁1/2倍跨距、1倍跨距以及2倍跨距处的节点偏差特征，采用线性插值方法拟合其他非节点处的偏差，通过偏差叠加方式获得线路时域不平顺数据。通过与实测数据对比分析可知，高速磁浮线路不平顺具有明显周期性，特别是垂向不平顺具有与桥梁一阶垂弯一致的周期频率；在短波（,λ,<,5 m）范围内高速磁浮谱高于传统轮轨谱，在中长波范围内高速磁浮谱介于中国高速无砟谱与德国低干扰谱之间。该不平顺的预测方法对已知建设规范的线路谱预测具有普通适用性。
Abstract
In order to predict for maglev track irregularity accurately, according to structure composition and technical characteristics of high-speed maglev track line, a irregularity fitting method of high-speed maglev track based on normal distribution superposition principle was applied. Based on the characteristic length of track (,l,=l 032 mm), the deviation characteristics was analyzed at the position of the length ,l, guide foundation length 3,l, bridge 1/2 span length, span and 2 times span. The deviations of other non-nodes were fitted by linear interpolation method, the time domain track irregularity data was obtained by deviation superposition. Compared with the measured data, it was found that the irregularity of high-speed maglev track was obviously periodic, especially, the vertical irregularity had the same periodic frequency as the first order vertical bending of the bridge; In the short wave range (,λ,<,5 m), the high-speed maglev spectrum was higher than the traditional wheel/rail spectrum. The range of medium and long waves of high-speed maglev was between the high speed ballastless spectrum in China and the low interference spectrum in Germany. The irregularity prediction method had general applicability to the line spectrum prediction of known construction technical requirement.
