In recent years, the tilting vehicle of air spring type, which uses air springs as the car-body tilt mechanism, has been employed even for Shinkansen trains to speed up on curved sections. On the test train with the tilt mechanism running at the speed of about 300km/h, however, it was found that the car-body roll and lateral vibrations increased in a compound curve where plane and vertical curves were overlapping. In this study, with an analytical model of the tilting vehicle of air spring type, numerical simulation is carried out to investigate the high-speed curving behavior in the compound curve. Then, anti-roll damper, which is equipped between the car-body and the existing anti-roll device, is examined as a counter measure. As a result, it is shown that the vibration phenomena occurred in compound curves is caused by the centrifugal force due to the vertical curve and the unbalanced stiffness between the right and left air springs for the car-body tilting, and that the anti-roll damper has a potential to reduce the car-body vibration increased in the compound curve.
