The low frequency noise of the ring - stiffened cylinder with double shell is depressed by increasing structure stiffness, the numerical simulation is adopted to evaluate the acoustics performance, find that the vibration and acoustic radiation of the structure could be depressed by increasing the structure stiffness within the discontinuous range of the low frequency
摘要通過增大雙層加肋圓柱殼的剛度降低低頻噪聲，使用數值模擬技術，評價結構的聲學性能，發現增大雙層加肋圓柱殼結構剛度，可在低頻段有限頻率范圍降低結構的振動與聲輻射。
