| dc.description.abstract | 本文研究具多孔材質之液體阻尼器的沖激行為，並以實驗的方式驗證理論的可靠性。假設流場為非旋性場及不可壓縮流，使得流場的速度勢滿足拉普拉斯方程式，並假設流場內的消能機制滿足達西定律，邊界條件為不可穿透性及自由液面的運動及動力條件，進而求解出暫態及穩態的速度勢。接下來建立阻尼器的等效模型，以方便分析阻尼器的動力行為。實驗方面，分別以衝擊及簡諧運動的方式驗證暫態及穩態的動力與水波特性。 | zh_TW |
| dc.description.abstract | The objective of the present thesis is to investigate the characteristics of tuned liquid dampers (TLD) with porous media. Assume that the flow in a tank is irrotational, incompressible and the damping force is proportional to fluid velocity based on Darcy’s law. TLDs with porous media represent the equivalent mechanical system that produces the equivalent forces developed by the sloshing fluid. The experimental studies involve impulse and sinusoidal excitations based on natural frequencies. Also, the energy dissipation has been studied. | en |
