Comparison on Track Spectra of Qinghuangdao-Shenyang Passenger Railway Line and German Railway Line

摘要

摘要: 从轨道谱的功率谱密度、时间样本幅值及对动力学性能影响的角度,对比了秦沈线轨道谱和德国轨道谱.秦沈线无碴轨道谱密度介于德国高干扰谱和低干扰谱之间,其中高低谱与德国高干扰谱接近,在30~45 m波长范围内方向谱优于德国低干扰谱.秦沈线有碴谱和德国高干扰谱互有优劣,方向和高低谱的分界波长分别是20 m和30 m.从时间样本来看,秦沈线无碴谱方向不平顺与德国低干扰谱非常接近,明显小于高干扰谱;有碴谱方向不平顺度略小于德国高干扰谱,但明显大于低干扰谱;无碴谱和有碴谱的高低不平顺均介于德国低干扰和高干扰之间.引起轮重减载的可能性大小依次是秦沈线有碴谱、德国高干扰谱、秦沈线无碴谱和德国低干扰谱.导致车体振动大小依次是德国高干扰谱、秦沈线有碴谱、秦沈线无碴谱和德国低干扰谱.

Abstract: The track spectra of Qinhuandao-Shenyang(QS) passenger railway line and German railways were compared in terms of power spectrum density(PSD),amplitude of time domain samples and dynamic performance.The PSD of the QS ballastless track(QSBLT) falls between those of German railway spectra of high irregularity(GRSHI) and low irregularity(GRSLI),with the vertical PSD of the QSBLT being close to that of the GRSHI,and the lateral one being better than that of GRSLI in a wavelength of 30~45 m.The order of PSDs of the QS ballast track(QSBT) and GRSHI changes at the critical wavelengths of 20 m and 30 m in lateral and vertical directions,respectively.In regard with the amplitudes of time domain samples,the lateral irregularity of QSBLT is very close to that of the GRSLI,and obviously smaller than that of the GRSHI;the lateral irregularity of QSBT is a little smaller than that of the GRSHI,but obviously larger than that of the GRSLI;the vertical irregularities of both the QSBLT and QSBT lie between those of the GRSLI and GRSHI.The rates of wheel load reduction are in the order of,from large to small,the QSBT,the GRSHI,the QSBLT,and the GRSLI.The carbody vibrations become severer under the GRSLI,the QSBLT,the QSBT,and the GRSHI.
