摘要: 利用压电陶瓷作为作动器,对柔性悬臂梁进行了振动主动控制研究.分析了压电结构振动主动控制的原理和方法.采用独立模态控制法对柔性悬臂梁的前两阶模态实施主动控制.实验结果表明,通过振动主动控制明显增加了柔性悬臂梁的结构阻尼,取得了十分有效的振动抑制效果.Abstract: The active vibration control of the flexible cantilever beam with PZT actuators was studied, and the principle and the method of theactive vibration control were analyzed. Using the independent mode space controlmethod, the active control experiment on the first-order and second-order mode vibration of the flexible cantilever beam was performed. The experiment results show that the damping of the flexible cantilever beam is increased significantly by introducing the active vibration control method, and the excellent vibration control effect is obtained.
