摘　　要：用实验方法研究了支架振动主动控制。结果表明，用压电陶瓷片作传感器和作动器，采用速度反馈控制，无论是谐和激励还是随机激励，支架振动都能得到有效抑制。振动控制中压电陶瓷片作传感器既简便易行，又减少了附加质量对被控结构动态特性的影响。Active vibration control for a supporter is experimentally realized. The experiment shows that, no matter how the supporter is excited, harmonically or randomly, its vibration may effectively be suppressed by using piezoceramic material as sensors and actuators to achieve velocity feedback controlling. The merit of the method is its convenience and that the piezoceramic devices are of lightweight and therefore have no much influence on the performance of the supporter.
