Based on a vehicle-turnout spatial couple model and the wheel/rail geometrical contact theories,the dynamic characteristics of the wheel/rail clearance and the relationship between the clearance and the lateral displacements of the wheelset and rails,wheel/rail lateral impacting forces and the wheel/rail contact angle are presented in this paper.

Analysis of wheel-rail unsymmetrical contact and wheel surface damage problem;

A new technique to reduce the wheel-rail wear is being researched by the railway departments in India.

Travelling speed is one of the main factors affecting wheel-rail deduced noise and it is obvious that the sound level will be increased according to the dependance of wheel-rail deduced noise on travelling velocity.

Rolling contact fatigue of wheel/rail and its advanced research progress;

Numerical analysis of influence of track excitation on normal load of wheel/rail in rolling contact;

Experiment research on wheel/rail adhesion characteristics for high speed railway;

The dynamic behavior of a wheel rail system was investigated.

Effects of structure deformations of wheelset/track on driving torque applied to a single wheelset of high speed locomotive;
