Car-body tilting vehicles have been employed to speed up on curved sections in the conventional railways. In this study, an analytical model for the beam-type tilt mechanism with the tilt angle of 5 degrees and the air-spring-type tilt mechanism with the tilt angle of 2 degrees are developed on the multi-body software SIMPACK. Using these models, numerical simulations are carried out and TC_T value which is the index of the riding comfort in the transition curve is evaluated from the simulation results. As a result, TC_T values of the air-spring-type are larger than beam-type because of the difference in lateral acceleration from the tilt angles. Then, for the air-spring-type, the TC_T values of height-control-type and pressure-control-type are compared. Their performances are almost same, although there are cases in which TC_T values of pressure-control-type are smaller than height-control-type.
