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.

The multi-body dynamic model of the high-speed train is established in order to study the failure effects of anti-hunting damper. Four kinds of failure case of the anti-hunting damper are compared, specifically including: one anti-hunting damper of the front bogie is broken; two anti-hunting dampers of the front bogie are broken; three anti-hunting dampers of the front bogie are broken; all four anti-hunting dampers of the front bogie are broken. The results have shown: when only one anti-hunting damper is broken, the influence to the dynamic performance of the high speed train is small, but once two anti-hunting dampers or more out of work, the critical speed of the vehicle decreases much more and the curve-passing performance also become worse.

The tests undertaken with train TGV 001 formed an essential part of the total SNCF high speed train research and yielded valuable information concerning bogie critical speed, factors affecting comfort, braking systems and train resistance. This information was valuable for the design of the high speed train sets for the new Paris — Lyons line but represents new fundamental knowledge of more general application.

This study describes the critical speed enhancement of the KTX-Sancheon, a Korean high-speed train, using measured wheel profiles. The wheel wear shape of the commercial high-speed train was measured according to mileage, and the relationship between conicity and mileage was investigated. The critical speed of the KTX-Sancheon power car was analyzed numerically with the measured wheel profiles. The suspension parameters were optimized to increase the critical speed of the KTX-Sancheon. As a result, the critical speed of the power car increased by 34.1% compared to its initial condition. The results are being used for a new design of the power bogie.
