In the test-measured contrast foundation of the ride comfort evaluations, the contrastive study was carried out on the influences of the airspring suspension features to the ride comfort and floor vibration of High-Speed Rolling Stock (HSRS) carbodies. Because of the different design styles on the orifice’s damping effective between the German and Japanese airsprings, the German airspring suspension remains therefore the ‘soft suspension’ under the high-speed operation, but the dynamical stiffness of the Japanese airspring suspension becomes harder remarkably, by which the vertical ride comfort of carbody is affected badly. When the vehicle velocity is raised above 300 km·h− 1, the vibration of 1st vertical floor bending mode begins to be appeared on the end parts of carbody, and increased gradually to the extent that the mode vibration of the local floor above bogie is brought into. For the German airspring suspension, when the secondary vertical damper is introduced, the unfavorable influence is produced on the carbody end floor vibration. And for the mid floor vibration, there is less relevance to the airspring suspensions.
