damping of sound radiation 中文意思是什麼
damping of sound radiation
解釋
聲輻射阻尼-
Matlab procedure is coded to compute the far - field sound pressure levels of the shell excited by radial point force. the influences of modal truncation, stringers, bulkheads and damping on the shell ' s far - field sound pressure are analyzed, laying down the basis for accurate analysis of the sound radiation from fluid - loaded reinforced double cylindrical shells
本文用matlab編製程序求解了單層殼在徑向激勵力作用下的遠場聲壓級,分析了模態截斷數、縱骨、艙壁板、結構阻尼等因素對殼體遠場輻射聲壓的影響,為準確計算加筋雙層殼在水下振動和聲輻射特性奠定了基礎。
