例如選擇省電的燈具安全的開關無毒的玩具可分解的尿布低輻射的電子設備簡易的資源回收工具省水衛浴設備環保冰箱冷氣含天然成份的化妝品非石化洗劑有機蔬果等，並進一步做廚餘處理及房舍內外綠化美化，如此不但可以降低對環境負面的影響，減少對己身健康的傷害，同時更可以提高生活品質，何樂不為呢？The structure - borne institute noise sending out by outdoor cabinet of air conditioning is calculated using fem / bem and software both commercial and self - developed
摘要採用有限元與邊界元耦合的方法，編寫了相應程序對空調室外機箱的激勵進行處理並對其結構聲輻射進行了計算。Structure - borne noise calculation radiation by out door cabinet of air conditioning using fem bem
法計算空調機室外機箱結構噪聲輻射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。In view of this case, the paper mainly studied sound radiation properties of structure, sound source identification methods, main factors affecting frame radiated noise and the common way to control the noise radiated by rotary machines. the detail research shows as fellows : ( 1 ) study on sound radiation properties of box - shape structure
根據這種情況，本文以旋轉機械結構噪聲為主要對象，比較系統地對結構聲輻射的性質、聲源識別方法、結構聲的主要影響因素以及旋轉機械結構噪聲控制的普遍方法進行了研究，具體研究內容如下： （ 1 ）箱形結構聲輻射性質的研究。A rectangular box simulating the axial box of the lathe tool is manufactured ; experimental measurements of the surface vibration on the rectangular box and the acoustic field around the rectangular box corresponding to firstly a series of a homogeneous excitation and secondly two iii independent white noise excitations are taken in a semi - anechoic chamber. taking the vibratory properties as input, the properties of the sound field are calculated by the evsbpm and the sdsbpm respectively. the effectiveness and reliability of the evsbpm and the sdsbpm for the calculation of acoustic radiation problem is further verified from the comparison of the calculated results and measured ones
第五章設計加工了一模擬機床主軸箱的長方箱體，在半消聲室環境下，分別對其在單點處一系列簡諧激勵作用下和兩點處的獨立白噪聲激勵作用下的振動及其輻射聲場進行了實驗研究和分析計算，通過計算結果和實測值之間的比較，進一步驗證了改進體積源邊界合肥工業大學搏士學位論文點方法和統計分佈源邊界點方法計算振動聲輻射問題的有效性和可靠性。分享友人
