Investigation on suppressing vertical bending vibration of railway vehicle carbodies is one of the main topic to improve the ride comfort of passengers. The authors have been developing the primary suspension damping force control system with variable damping axle dampers, which isolate the bogie frames and the carbody from excitation input due to the track irregularities. Reducing the vertical vibration of the bogie frames is generally effective to suppression of the bending vibration of the carbody. The authors, however, have experienced some cases in running tests, where the bending vibration is not suppressed nevertheless of the reduction of the vibration of the bogie frames. The authors therefore focus on how longitudinal coupling devices among vehicles influence on the bending vibration. The analytical model including the longitudinal coupling devices is composed in this study. It is verified with the numerical simulations that the bending vibration of carbodies can be influenced by such devices.
