Abstract
In recent year, 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 due to the deterioration of the body rigidity. Recently, passive vibration suppression with piezoelectric elements which are shunted by electrical circuits is paid attention in order to control vibration of structure. This report shows the experimental results using 1/6-scale experimental setup attached stack type piezoelectric actuators. In the experiment, a serial connected inductor and resister circuit use as shunt circuit. Moreover, including the negative resistor in the circuit reduce the internal resistance of the inductor in order to tune the shunt circuit optimally.
