The primary factor affecting the wheel-rail force is the short wave track irregularity.

Dynamic response of linear metro vehicle/track excited by track irregularity;

PSD analysis of track irregularity of continuously welded rail track in test zone of qinghai-tibet railway;

Development forecast model of track irregularity based on probability distribution;

A time domain covariance method for the trainbridge vertical stochastic vibration excited by the time-correlated multidimensional nonwhite noise rail irregularity was proposed.

To obtain rail irregularity samples for train-bridge vibration control and stochastic analyses,a simulation method of irregularities at all axles of a train was investigated.

Dynamic analysis was used by train-bridge model to elevated railway system considering rail irregularity.

Spectrum Analysis of Non-uniformly Sampling Signal of Track Irregularities;

To ensure safe and stabile running of both passenger and freight trains on the same line, the relationship between train running safety and stability and track irregularities must be studied.

In order to analyze vibration of high-speed railway tracks with geometric irregularities,receptances of the vehicle at the wheelsets and the track at the wheel-rail contact points are derived,an analytical model for moving vehicle-track vertical coupling vibration is established by considering moving axle loads and track irregularities.
