acoustic coupling system meaning in English

声耦合系统

( 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
讨论了阻尼降噪问题，建立了有阻尼声振耦合系统的有限元模型，采用振型叠加法，将系统位移转换到以固有振型为基向量，进行结构壁面有吸声材料的声振耦合系统响应的有限元分析与灵敏度分析，推导了比例阻尼条件的灵敏度计算公式。
