Abstract
In recent years, railway vehicles are becoming lighter since it corresponds to improvement in the running speed. However, this affects a degree of ride comfort as increase in bending vibration for which it comes from the deterioration of the body rigidity. Recently the piezo-electric element are paid attention as the actuator for structures in order to control vibration. This refers as the smart structure concept. A piezo-electric element has characteristic that is small, light and high output. Therefore, the objective of this research is to reduce bending vibration by equipping piezo-electric element in the body. In addition, an active control is applied to the secondary suspension, and the rigidity vibration the car body is decreased. Vibration control performance is investigated by computer simulation.
