| 中文摘要: |
| 本文以矩形的板-箱系统作为研究模型.探讨了在外界声源激励下,弹性薄板受激振动,辐射入箱内噪声的形成机理.并分析了选用压电片作为激励器,进行箱内噪声主动控制的原理.在此基础上,对3种控制方案进行了分析比较,得出了最优方案. |
| 英文摘要: |
| The rectangular plate cavity system is selected as research model in this paper.The mechanism of transmission noise given off by vibrating plate stimulated by outside sound source is discussed.Then piezoelectric plate (PZT) is selected as actuator,ultimatum of active control on structural interior noise is another focus.On the basis of these theories,three control schemes are analyzed and compared,then the best scheme is confirmed. |
