介绍了压电元件在抑制铁道车辆车体弯曲振动中的应用。元件电连接到外部分流电路。作者利用装有压电元件和附加装置组成的阻尼器单元的通勤车进行了稳态激振试验。在测试中实现了两种类型的分流电路，电感器和电阻器串联（L-R电路）以及具有负值的电容器和电阻器（负C-R电路）。试验结果表明，阻尼器单元在固有频率处将地板上的激振力和加速度之间的频率响应增益减小到约30%。
This paper describes the application of piezoelectric elements to suppress the bending vibration of a railway vehicle carbody. The elements are electrically connected to external shunt circuits. The authors carried out stationary excitation tests by using a commuter car with damper units consisting of piezoelectric elements and attachment devices. Two types of shunt circuits, an inductor and a resistor in series (L − R circuit) and a capacitor with a negative value and a resistor (negative C − R circuit), are implemented in the tests. The test results indicate that the damper units reduce the frequency response gain between excitation force and acceleration on the floor at the natural frequency up to approximately 30%.
