There are two types of car-body tilting mechanism for railway vehicles. One is the beam-type tilt mechanism with the tilt angle of about 5 degrees and the other is air spring-type with the tilt angle of about 2 degrees. Since the tilt angle of air-spring-type is too small to reduce stationary lateral acceleration dramatically, the investigation is targeted at the tilting control law and the vibration suppression for the improvement of riding comfort. In this study, analytical models of air-spring-type tilting vehicle are developed using the multi-body software SIMPACK. Using two control methods, the height control and the "height + internal pressure" control, there effects are examined in the simulation. The results were compared with the results from test plant. Consequently, it is shown that the addition of internal pressure control may reduce the roll vibration and potentially contribute to the improvement of riding comfort.
