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

  • 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.
