Based on the kinematical design criterion of equi - chord percent ratio and spatial rigid body guiding mechanism, three theoretical design methods of arc track, non - arc track, and helical track are proposed in this thesis, meanwhile, different design methods about prime flap and sub - flap driving mechanisms are completed. three cases of different three - gaps - fowler - flap tracks are designed
對后緣三縫富勒襟翼工作時的3個關鍵位置，按照「等弦長百分比」運動的設計準則和空間剛體引導機構的設計思路，提出了圓弧軌道、非圓弧軌道和螺旋線軌道等3種空間位置引導軌道的設計原理，並分別給出主襟翼和子襟翼驅動機構的不同設計方法。The stability behavior of kiewitt ' s suspen - dome was analyzed on the initial state. by the geometrical nonlinear finite element method, the equilibrium path is traced using the cylindrical arc length technology and incremental newton - raphson method. the influence of kinds of parameters is studied
採用非線性有限元理論，結合牛頓荷載增量法和柱面弧長法的跟蹤技術，對kiewitt型弦支穹頂結構進行了考慮幾何非線性的全過程分析；為了掌握各個參數對靜力穩定性的影響程度，進行了參數分析。It builds a relative coordinates based on the jumping - off point of circular interpolation as its origin, caculates the sine and cosine of the angle formed by x axis and the line which connects the origin and the centre of the circle, then gets the coordinates of the centre in the relative coordinates, and enduces a uniform fomula, which is easy to program in computer
摘要用圓弧插補起點作為相對坐標系原點，連接圓弧起點和圓心，求出該連接線和相對坐標x軸的夾角的正餘弦值，由此解出圓心在相對坐標系的坐標，並得到一個統一的計算公式，易於計算機編程實現。Arcsine in degrees or radians - this. bas module inlcudes functions that take a sine value as a parameter and return the corresponding angle in degrees or radians
