| dc.description.abstract | 當一導體線圈在磁場中運動，依據電磁學理論，會產生感應電流，此感應電流會形成與運動方向相反之勞倫茲力，控制線圈移動。利用此原理，製作出一電磁阻尼器，將阻尼器安裝於振動系統上，以有效減緩系統振動的振幅。在本文中，先進行單自由度的被動式與主動式控制實驗的數值模擬，之後以未外加任何感測元件與外加能量，將阻尼器應用在懸臂梁的振動控制上進行被動式控制實驗，改變影響控制效果的各個參數(頻率、線圈匝數)，並與模擬結果相互印證，發現振動的振幅確實能夠有效降低。在主動式控制實驗中，則是利用外加電子電路，放大感應電流與勞倫茲力，更進一步改善被動控制效果。最後，以噪音訊號(noise)輸入系統激振，亦有良好的減振效果。 | zh_TW |
| dc.description.abstract | In accordance with electromagnetic theory, when a conductive wire moves in a uniform magnetic field. It will generate an inductive current. And the charges of this induced current under the action of applied magnetic field experience a Lorentz force, and pass this Lorentz force whose direction is opposite to the moving direction of the wire, to the wire. According to this counteracting phenomenon, we make an electromagnetic damper and apply it to vibration control of cantilever beam. In this thesis, we first establish equations of vibration and simulate numerical active and passive. Next, we perform experimental test of passive vibration control and study the effect of system parameters on the alleviating the vibration amplitude. This agrees will with simulation results. In the active vibration control experiment, we add an electric circuit which can amplifier Lorentz force and therefore improve the control result. Finally, we also perform the experimental test of noise control and find that the result of amplitude reducing is very good. | en |
