| 中文摘要 | 本研究乃是針對平板結構振動,首先於理論上推導出四邊完全固定之正方形平板 結構之壓電感測器靈敏度以及壓電致動器之出力強度外,實驗上更以壓電陶瓷作為感測器及 致動器作單頻的主動式振動控制。實驗方法為由信號產生器產生一信號,激發鋼板,使鋼板 產生振動,再由感測器感測到之信號經由濾波器與功率放大器將信號放大後,傳送到致動器 以達到反制效果,控制結果最高可達到 15.65 dB 的振動降低量。 |
| 英文摘要 | An active control approach for plate vibration is studied. Piezoceramic sensors and actuators are employed. The sensititivity of the piezosensors and the output power of the piezoactuators are derived, respectively, for clamped rectangular plate when bonding is perfect. The experiments for single mode control are also conducted. The plate vibration is generated by a signal generator and sensed by the piezo-sensor. After the sensing singnal being filtered amplified and fed back to the piezo-actuator the vibration is controlled. The control effect is as high as 15.65 dB down. |
