中文摘要 | 本論文主要的目的是研究含流體樑之扭轉振動。樑受扭轉負荷於機械工程的領域 的應用上是非常廣泛的。本論文將從樑元素與流體元素的觀點建立含流體樑之扭轉振動的運 動方程式,然後解其運動方程式,以得到固定-固定邊界條件之扭轉頻率響應與扭轉模態。 而且,本研究除了理論模擬外,並進行不含流體與含流體樑之扭轉實驗分析。結果顯示,理 論模擬與實驗分析二者非常吻合。本研究的結果將可提供工程應用上的重要參考價值。 |
英文摘要 | The purpose of this paper is to study the torsional behavior of a beam containing fluid. A beam subjected to torsional loading frequently appears in mechanical engineering applications. The equation of motion is established from the standpoint of free-body diagram of a beam element and a fluid element. The torsional frequency response of a beam with fixed-fixed boundary condition is constructed and the effects of fluid are also included. Also, experiments are performed to compare with the simulation results of theoretical torsional natural frequencies. Good agreement is obtained between simulation results and experimental results in this paper. The results of this study can be supplied to in engineering application. |
