Failure Effects of Anti-Hunting Damper on High-Speed Train

Abstract:

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.
