A solution research for china millennium monument rotation noise testing
中華世紀壇旋轉(zhuǎn)噪音測試方法的研究
The cooling fan noise comprises the rotation noise and the turbulent noise
風扇噪聲由旋轉(zhuǎn)噪聲和湍流噪聲構(gòu)成。
The turbocharger noise is formed by the rotation noise resulting from the periodical air cutting of the fan blade and the turbulent noise of high - speed gas flows . as a continuous high frequency noise , it mainly falls between the 500 to 10 000 hz range
渦輪增壓器的噪聲是由于葉片周期性地切割空氣產(chǎn)生的旋轉(zhuǎn)噪聲和高速氣流形成的湍流噪聲而形成的，是一種連續(xù)性的高頻噪聲，主要分布在500 ~ 10000hz的頻率范圍。
In order to analyze the rotation noise further , a new method for measuring the amplitude and phase of each harmonic component of periodic signal mixtures is established based on the morlet transform and fourier transform in theory , which will provide scientific warranty for reducing noise of disk mill
為了進一步分析爪式粉碎機的旋轉(zhuǎn)噪聲，理論上利用morlet小波變換結(jié)合fourier變換對旋轉(zhuǎn)噪聲各次諧波成分的振幅和初相位的提取，作了初步探討。
Taking the ffc ? 23a disk mill as a specimen model , the rotation noise generated from the interaction between fixed claws distributed on the outer and inner circle of the fixed claw plate and the corresponding moving claws has been separated in an experimental study by the modern analytic method of acoustic . thereby , a conclusion that the principal component of rotation noise in disk mill comes from the interaction between the fixed claws on the outer circle and the corresponding moving claws has been reached . in accordance with the above , modified noise reduction design for the structural parameters such as the number of claws on the fixed claw plate , shape of claws and the relative positions of the claws arranged on the outer circle and inner circle has been carried out
