PSD of ballastless track irregularities of high-speed railway [PDF]
SCIENTIA SINICA Technologica, 2014 The calculation method, fitting function and fitting spectrum of power spectral density (PSD) of track irregularity were proposed in the paper. To improve the calculation accuracy of PSD of track irregularity, a linear interpolation method and a wavelet analysis method are given and used to eliminate the outliers and trends in the track irregularities.

The Service Life of Ballastless Track
Procedia Engineering, 2017 Abstract Before the widespread use of high-speed rail ballastless track needs to be tested in real conditions at high speed and small axial load. Experimental railway track of “VNIIZhT” makes it possible to carry out tests at high axial load, low speed but that does not fully meet the real fields of application of ballastless track.

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.The theoretical and analytical approaches of stochastic dynamics constitute the foundation for performing in‐depth inquiries into the random dynamic behavior of high‐speed railway vehicle–track system (RVTS). The proposal of the generalized probability density evolution method (PDEM) has opened up new perspectives for the stochastic dynamic analysis of
