In order to reduce traveling time for passengers while maintaining constant ride comfort, tilting trains have been developed and prevailed. However, the tilting system has a certain problem causing possible motion sickness. The authors are involved in development of a new tilting system to prevent passenger's motion sickness. The new system was applied to a tilt actuator by electro hydraulic power. Good results in running tests were obtained. However, the system is required to reduce costs. Therefore, the authors decided to work on improving the performance of pneumatic servo control system which is used in the current tilting system. In this paper, a numerical simulation model of the pneumatic servo system, which is based on the state equation of air, was constructed. The validity of a proposed model and the effectiveness of a proposed system were demonstrated by comparison with results of experiments. In addition, simulation results showed that the proposed system suppressed low-frequency lateral vibration which might cause motion sickness.
