coupled cavity technique
解釋
耦合腔技術-
( 3 ) introducing the proportional damping, the finite element formula of structural - acoustic coupled system lined with sound absorbing materials is obtained. mode - superposition technique for modal frequency response analysis of coupled structure - acoustic systems is also used to deal with the sensitivities of the eigenvalues and eigenvectors of coupled systems for the purpose of reducing cavity interior noise in theory
討論了阻尼降噪問題,建立了有阻尼聲振耦合系統的有限元模型,採用振型疊加法,將系統位移轉換到以固有振型為基向量,進行結構壁面有吸聲材料的聲振耦合系統響應的有限元分析與靈敏度分析,推導了比例阻尼條件的靈敏度計算公式。
