In light of the limitation of fast fourier transform ( fft ) for the method of traditional spectrum analysis to analyze the unsteady signal, wavelet and wavelet analysis are made for the typical unsteady process signal of starting up and shut down with the good characteristic of simultaneous localization in both the time and the frequency domains based on the field test on the vibration of two - row placed units in lijiaxia hydropower station, in which the signal is decomposed into different frequency band, and then the weak signal is caught and the dominant frequency is picked up for the analysis of the vibration source
摘要基於李家峽水電站雙排機組振動的現場試驗研究,並且針對傳統頻譜分析方法傅立葉變換( fft )對于非平穩信號已力不從心這一缺陷,利用小波分析方法在時域和頻域上同時具有良好的局部化性質,通過對開停機這一典型非平穩過程信號進行小波及小波包分析,將其分解到不同頻帶內,獲取微弱信息和提取優勢頻率,並對其作振源分析,得出開停機初始時刻因水流不穩均出現強烈的振動現象,且低頻段信號能量最大,開停機過程水流脈動壓力和尾水渦帶擺動是引起定子基礎振動的主要原因。Although the flux per revolution of the optimized pumps is a little smaller than that of tatsuno combined pumps, other characteristics, such as fluctuation rate, maximum pressure angle and velocity fluctuation rate etc, are much better. the methods to cut gears are proposed in the theory for the practical produce in the future
雖然,在體積相等的條件下,優化出來的外圓弧包絡線內嚙合齒輪泵的排量略小於tatsuno組合泵的排量,但其它性能(如:流量脈動率、最大壓力角、速度波動量)都更優。Giving some suggestions to develop the fuel according to the experiment result. the final experiment result is very good. after using alcohol - blended diesel oil in diesel engine, the power can be achieved, the let of contamination is reduced, thermal efficiency enhanced, the exhaust degree and the max combustion pressure is steady
對理論和實驗結論進行總結,對課題的發展提出建議實驗的最終數據證明:在柴油機上燃用乙醇柴油后,能夠達到原機的功率,並且柴油機的排放狀況有很大的改善,熱效率有一定的提高,排氣溫度和最高燃燒壓力基本不變,實驗結果是比較理想的,可以考慮在實際中應用和推廣乙醇柴油。When the condensation of water increases, the bucket loses buoyancy and makes the machinery reversely seal to generate differential pressure, the main valve opens and obtains large displacement, steam equipment prompt starts to maximize the thermal efficiency of steam equipment
當凝結水量增大時,吊桶失去浮力使得機構反向密封而產生壓差,主閥開啟而獲得大排量,用汽設備迅速啟動,最大限度地發揮出用汽設備的熱效率。From the pressure of living space in a country to the narrowness of private space, even the difficult question of survival or destroy in philosophical choice. there is a dilemma because of the infinitive utility space and its limited maxi - mum arrangement
大至國家「生存空間」的壓力,小至日常生活中「私域空間」的狹小,甚至哲學選擇中的「生存或毀滅」難題,無不表現出某種因效用空間的有限而無法最大化地排列不同效用的二難處境。分享友人
