Theoretical and Practical Study on High-Speed Bogie Stability Margin Regulations

Piao, M. W. / Liang, Shulin / Kong, W. G. / Fang, Z. G. / Zhao, W. Z.

Since the initiation of 200 km·h^− 1 High Speed Railway (HSR) in the Japanese Shinkansen, the lateral stability solutions of High Speed Rolling Stocks (HSRS) have been developed and improved through the theoretical and practical courses, especially the novel theory of anti-hunting wide-band absorption is presented and put into Chinese 300 km·h^− 1 HRS practices. The lateral vibrations of some motor-vehicle coaches are experienced during the test running of 16-vehicle train with CRH380B bogies in Jinghu HSR line. Based on the contrastive data from anti-hunting damper testrig, the determining criterion was formulated definitely for the in-series stiffness. After the comparison with the acceptance tests, it is further pointed out that the radical reason for the above coaches’ lateral vibrations is that the in-series stiffness of anti-hunting dampers is too hard so that the stability margin of rear bogie is reduced much, and the direct factors are due to the wind load interactions and longitudinal eccentric loads which cause their wheel sideslips. The anti-hunting soft-constraint technique strategy is therefore proved to be the successful and effective solution, in which there exists a theoretical optimal value of the in-series stiffness to trade off the stability of trailer bogies and the handling performance of motor bogies.
