Abstract
In recent years, the car-body tilting mechanism using air springs is employed for shinkansen trains to speed up on curved sections.In this study, two analytical models, which can tilt the car-body based on the internal pressure of air springs, are developed. One model utilizes the change of air spring stiffness, and the other does the upward force resulting from the internal pressure of air springs.The numerical simulation shows the following results. The vehicle behavior of the two models are almost equal and they can reproduce the measurement data of actual vehicles on a curved section with vertical curve.
