With the rapid development of high-speed railways, wheel and rail wear has become increasingly serious due to the acute wheel-rail interaction. During the operation of high speed vehicle, complicated wheel-rail contact force will lead to wheel profile wear, which will worsen the dynamic performance of vehicle system, or even influence the safe operation of vehicles. In order to ensure the vehicle dynamic performance, right now regularly wheel re-profiling has to be adopted. Therefore, the study of wheel profile wear and its effect on vehicle dynamic performance is very important [1,. The purpose of the paper is to study the variation characteristics of vehicle dynamic performance with respect to the wheel profile wear through numerical simulation and field test.

As the speed of high-speed train become more and more fast, anti-hunting damper become a must to high-speed train which can increase the critical speed of the train effectively. Now some kind of high-speed train operating at the speed of 300km/h has installed four anti-hunting dampers for every bogie. As the number of anti-hunting dampers increased, the probability of anti-hunting dampers failure is also increased. This paper will increase the critical speed of the high-speed train up to 300km/h by optimal design of wheel profile, which can drop the number of anti-hunting dampers per bogie from four to two meanwhile.

Equivalent Conicity

In order to reduce wheel profile wear of high-speed train and extend the service life of wheels, a high-speed vehicle multi-body dynamic model and wheel profile wear model are established, in which the wheelset is considered as flexible. The influence of wheel profile, track gauge, and rail cant is extensively studied. The simulation results show that the type XP55 wheel has smallest cumulative wear depth, and type LM wheel has largest wear depth. It is known that the equivalent conicity of the wheel should not be too large or too small. The track gauge with 1435-1438mm and rail cant with 1:35-1:40 can have better wheel wear performance.
