“…(1) , and have been extensively studied (2) . Since it has been mainly applied to small structures (3) (4) , however, it is expected to deal with considerable problems when applying to such large structures like railway vehicle carbodies. Therefore, the authors have presented investigations to reduce the bending vibration of a primitive beam structure with length about 3m (5) as the primary step to realize the above goal.…”

Piezoelectric elements, which are electrically connected to external shunt circuits, are introduced to suppress bending vibration of a scale model of a railway vehicle. The authors proposed two types of shunt circuits aiming at practical use. One circuit is equivalent to an inductor and a resistor in series, and the other a negative capacitor and a resistor, and both circuits are designed for use under conditions of large vibration amplitude that causes high voltage generated by the elements. Results of excitation tests show that the first bending mode of the scale model can be suppressed successfully. Moreover, the circuit including the negative capacitor can also reduce vibration associated with higher eigen modes simultaneously with the first mode.
