機殼輻射 的英文怎麼說
中文拼音 [jīkéfúshè]
機殼輻射
英文
cabinet radiation-
The impact on the muffler performance is realized by the high - speed pulsation gas flow, which regenerates noises and strikes the acoustic elements of the muffler such as the pipe run, the body case and the separator plate to arouse the vibration radiated noise
氣流影響消聲器性能的主要原因是發動機排氣的高速脈動氣流再生噪聲，其次是這種氣流會沖擊消聲器的管路、殼體、隔板等聲學元件，進而激發振動輻射噪聲。The noise of such structures root in the shell vibration that drove by the inner engine, when coupled with the liquid medium, the noise will affect the performance of the vessels badly
這些航行器的結構噪聲來源於內部機械激勵殼體振動，並帶動周圍流體介質振動產生聲輻射，它嚴重影響了水下航行器的整體性能。The frame radiated noise is one of the major noise resources of rotary machines, especially for gear case which has close shell and vibrating screen which works in vibrating ways, the frame radiated noise energy account for more than 90 % of total sound energy. so if we could not successfully resolve the problem, the noise of rotary machines would never be effectively controlled
結構噪聲是旋轉機械的主要噪聲源之一，尤其是對于如齒輪箱這類具有封閉殼體的機械和如振動篩這類以振動為主要工作方式的機械，結構振動輻射聲能占總聲能的比例甚至可以達到90 95 ，因此不解決結構噪聲問題旋轉機械噪聲就不能得到有效的控制。
