礦用軸流式風機葉片的模態分析

Modal Analysis of Mining Axial-Flow Fanner's Blade

    摘要
  • 摘要: 針對礦用軸流式風機葉片的斷裂現象,依據模態分析的基本原理,提出了葉片模態參數的測試方法和葉片的調頻方法,并對70B2型風機葉片進行了模態分析。

     

    Abstract: For the breaking phenomenon of mining axial-flow fanner's blades, based on the fundamentals of modal analysis, the measuring method of the blade's modal parameters and frequency modulation method of the blade are put forward,and the modal analysis of 70B2 Axial-Flow Fanner's blade is completed.
