中文摘要 | 本文是利用統計能量法,計算因船舶主機振動所產生的振動傳遞及其散發至水中 之噪音量,並建造一船體機艙模型,進行振動能量傳遞及水中噪音實驗。最後將實驗的結果 與由統計能量法所計算的結果相互比較。實驗與理論的結果比較在預測之頻域內,大多僅相 差數 dB 左右,證實此方法可用於船舶振動與水中噪音傳遞之預估。 |
英文摘要 | The Statistical Energy Method was used in this paper to predict the amount of vibration energy transmitted to the ship hull and to the surrounding water due to engine vibration. A model of engine room was built to perform the vibration and underwater noise tests. Comparisons of the results show good agreement between the predicted and the measured vibratory energy. |
