Peak updraft strength is slightly enhanced with hodograph curvature, 29. 0 m / s in b versus 26. 1 in c
山頂上升氣流強度隨速矢端跡曲率加大而稍有加強,在(圖上) b點是每秒29米, c點是每秒26 . 1米。The results of calculation and measures show that the low frequency of steam pipelines vibration fastens on 4. 3 to 4. 5 hz and 9. 5hz, the low modes fastens on one - steps curl in vertical plane and its plane of each steam pipeline and one - rotation along with the line connecting the port circling main steam gate and the horizontal port of unit. the modes of # 3 and # 4 main steam conduits occupy the majority of low steps modes ( the five of the first eight phases ), except for the first phase rotation vibration, the maximal distortion of other low steps vibration modes are all caused by the vibration of erect pipelines of cylinder
計算和實際測量結果表明:導汽管低頻振動以4 . 3 - 4 . 5hz 、 9 . 5hz頻率為主,管系的低階模態以各導汽管在垂直導管平面和平面內的一階彎曲、以及繞主汽門處端點與水平段汽機端連線的一階扭轉為主, # 3 、 # 4導汽管的振動模態占低階模態的多數(前八階模態中的五階) ,除一階扭轉振型,導汽管的其它低階振動模態中都是進汽缸立管的下端振動變形最大。Presents a new method of constructing boundary conditions for nurbs interpolotion, which makes it unnecessary to know the deriratives of curve ends, and solves the problem of zero curvature at curve ends, and enables designers to control the shape of the two end segments of curve easily and freely by simply adjusting the curvature coefficients and discusses the influences of curvature coeffients on the shape of the end segments of curve
提出一種新的用於nurbs曲線插值的構造邊界條件的方法.該方法不需要已知曲線端點的切矢,並且解決了端點曲率為零的問題;它使得設計者可以通過簡單地調整首末端點曲率參數便可以隨意地且很容易地控制曲線首末兩段曲線的形狀.最後還討論了曲率參數的取值對曲線端部形狀的影響The expressions of distributed bars of several normal cases in the practical engineering are presented based on the equalization of the slope of prestressed bars at the end of each curve at inflection point
以預應力筋在反彎點處每段曲線端點的斜率相等為基礎,提出了實際工程中常用的幾種情況的布筋表達式。分享友人
