项目摘要

In this study, a wave absorbing technique, i.e. the technique which cancels the reflection wave at the end point of the flexible thin structure, was investigated using piezoelectric films. At first, a cantilever beam, which can be applied to the flexible rotating arm, was introduced as the controlled structural model. Then, a smart cantilever beam, on which appropriately shaped piezoelectric film sensors and actuators were bonded, was manufactured. Theoretical analysis and experiments were performed and it was shown that vibration control effects will be expected for broad band frequency range including several vibrational modes. Furthermore, vibration control effects in the laboratory experiment showed good agreement with those in the theoretical analysis when the excitation frequencies were low enough. It was also confirmed that it is difficult to apply the proposed method to the flexible rotation arms, since the influence of the inertial force cannot be neglected in the experiments.

在本研究中，利用压电薄膜研究了一种吸波技术，即在柔性薄结构的末端消除反射波的技术。首先，引入可应用于柔性旋转臂的悬臂梁作为控制结构模型；然后，制造了一种智能悬臂梁，在其上结合了形状合适的压电薄膜传感器和执行器。理论分析和实验结果表明，在包括多种振动模式的宽频带范围内，振动控制效果良好。此外，当激励频率足够低时，室内实验的振动控制效果与理论分析结果吻合较好。实验还证实，由于惯性力的影响在实验中不能忽略，因此该方法难以应用于柔性旋转臂。
