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;

Effects of water medium on adhesion of wheel and rail;

Based on the numerical method for the contact of wheel and rail with a water medium, a numerical method of analyzing the adhesive force between high speed wheel and rail with a water medium is developed under the condition of neglecting the part of traction forces transferred by the water medium.

Based on the partial elasto hydrodynamic theory,a numerical analysis method is developed that can solve the contact of wheel and rail with water medium at higher speed.
