摘要針對轉子式稠油泵在運行中因流量和壓力脈動所引起的劇烈震動和噪聲,在稠油泵出口安裝金屬伸縮節和緩沖罐,有效地降低了震動和噪聲。The motion of the shell due to an impulsive pressure may be examined in the same fashion as in the case of the cylinder problem.
由脈沖式的壓強引起的球殼的運動,可以按照在圓管問題中所用的同一方式來進行分析。Several key techniques of carving and milling machine cnc system are deeply studied they include : the transformation, data rebuild and interface design of huge volume nc program produced by cam ; the algorithm of cubic parametric spline pre _ interpolation and high speed real time interpolation in the cnc system, which. will gain a much higher surface precision and cutting speed ; methodology and algorithm of movement velocity acceleration control on a real time forecast _ and _ prejudge basis is designed. therefore, a smooth movement is insured. the shake and noise problem caused by non _ uniform pules for driving stepping or servo motor is solved by an improving algorithm to generate uniform pules
同時,本文對基於統一的pc平臺的雕銑機數控系統中的幾項關鍵技術進行了深入的研究,包括: cam生成加工程序的傳送、接收、讀取及其加工鏈表的生成和實時重構;對cam生成的離散數據進行三次參數樣條插值和基於累加弦長的三次參數樣條插補控制,保證加工工件表面的精度和光順性;設計具有「前瞻」功能的自動升降速控制方法,保證加工過程的平穩性;通過脈沖均勻化,有效地解決加工過程中因為脈沖不均勻而引起的震動問題。It preliminarily establishes a set of test theory and technical approach to wind tunnel test. specifically speaking, it includes following work : ( 1 ) theoretical analyses on key parameters of ao effect were made. from maxwell equation, the computation formula for focusing intensity of ordered disturbance and the computation formula for pulse peak intensity were derived
