Vibration Control of Air Spring Type Tilting Train

抄録

This paper aim to improve an efficiency and a performance of a control system design by integrating a tilt control and a vibration control for a car-body tilting vehicle using air springs that have been conventionally treated separately. In this study, as a basic study, equations of motion for a 6 degrees of freedom railway vehicle model including air springs were formulated. Then simultaneous control of the tilt and the vibration was performed by linear quadratic integral control to the model. The effect of the vibration control was confirmed. Frequency response of simulation results of a vibration control of a vertical motion. The peak gain decreased by 14[dB]. And, frequency response of simulation results of a vibration control of a roll motion. The peak gain decreased by 19[dB]. A followability to the target value is confirmed when the target tilt angle is input as a step. The tilt angle of the car-body reaches the target tilt angle in about 2 [sec]. In addition, the car-body tilt angle converges to the target tilt angle without vibrating. As results of a control simulation, the effectiveness of simultaneous control of the tilt and vibration of the car-body tilting vehicle using air springs was confirmed.
