  1. In this paper, the effect of disc muffler on vibration and sound radiation of worm shell is discussed

    摘要探討了圓盤型進氣消聲器對蝸殼振動和聲輻射的影響。
  2. The reason that the noise is lower with inclining tongue is : 1 ) both the radius of the tongue and the gap between the tongue and the blade are changed across the wideth ; 2 ) the phase angle between blade and the tongue is changed across the wideth, therefore the peak value of the noise do not appear at the same time, so the peak value of the noise with inclining tongue is much lower than the straight one. the influence of the expanded angle of the shell of the fan on the noise was invested experimentally, and the optimal angle was got

    傾斜蝸舌降噪的主要原因是：一是改變了從氣流入口側到風機輪盤的蝸舌間隙和蝸舌半徑；二是改變了葉輪與蝸舌非定常相互作用的相位差，使其產生噪聲也有相位差，迭加的結果進一步降低了噪聲。另外，試驗研究了不同蝸殼擴張角對風機噪聲及效率的影響規律，蝸殼擴張角選擇當否，對效率和噪聲影響較大。
  3. It requires more even airflow and avoids the tremble of the compressor and the instability of gas turbine. at the same time, the dimension of the inlet volute must be as small as possible, so that the gas turbine can work well

    一方面，它要求流經進氣蝸殼的氣流盡量均勻，以免造成壓氣機的喘振和整個動力裝置性能的不穩定；另一方面，要求進氣蝸殼結構尺寸在保證要求的前提下盡量小，有利於機艙的布置。
