對于箱形截面主梁,本文介紹了三桿比擬法上、下翼板中比擬桿的計算公式,以及在典型荷載和支承的情況下翼板內各桿的應力計算公式,並對多箱式主梁截面進行合理簡化,使三桿比擬法應用於多室箱梁的剪力滯分析。Abstract : the effects of airfoil geometric parameters on wing " s spacial and polarized scattering characteristics have been systematically revealed. the results of the study indicated that the calculating value of diffraction from trailing edge by using the formula of the straight wedge is very far from experimental results for vertical polarization, and the contribution of thickness of the trailing edge to scattering must be considered in the calculation. the scattering peak of leading edge depends only on radius of airfoil for horizontal polarization. but for vertical polarization, it depends on maximum thickness and the location of maximum thickness. engineering formulas for evaluating all scattering peaks were given in the paper. it is important for the design of low - rcs wing
文摘:系統地揭示了翼形幾何參數對機翼的空間散射特性、極化散射特性的影響規律.研究發現,在垂直極化狀態下用理論尖劈公式計算機翼后緣繞射的計算結果與實驗結果相差甚遠.提出在垂直極化狀態下機翼后緣繞射的計算必須將后緣厚度考慮在內的見解.對於水平極化,前緣散射波峰只與前緣半徑有關;而對於垂直極化,前緣散射波峰與翼形最大厚度以及最大厚度位置有關.給出前後緣散射波峰的工程估算公式,為低雷達散射截面( rcs )機翼設計提供依據Plastic theory suggests, the composite beam for the floorslab is suited lower flange, it s plastic limit moment cuts down by 52. 4 % than the composite beam for the floorslab is suited on the top flange. it s plastic limit moment lifts 8. 8 % than the steel beam, which is on the same condition
塑性理論分析的結果表明,樓板位於鋼梁下翼緣形式的組合梁和樓板位於鋼樑上翼緣形式的組合梁截面相比較,其塑性極限彎矩降低52 . 4 ,和同等條件下純鋼梁截面相比較,樓板位於鋼梁下翼緣的組合梁塑性極限彎矩提高8 . 8 。As for side box girder, the elastic theoretical solution has been introduced. the method is based on stress function and regards side box girder as combine of plate element and shell element. then the force and stress formulae for flanges have been derived
對于邊箱式截面主梁,本文介紹了彈性理論解法,基於翼板單元應力函數,將邊箱梁視為板單元和筒殼單元的組合體,從彈性力學出發,推導出板中法向應力。The form of variable cross - section, used mostly in the practical projects, just has the change of the linear variation on the height of the web plate while keep the width of the flange c hangeless
實際工程中使用最多的變截面構件形式是僅構件腹板高度線性變化,翼緣寬度保持不變的形式。Double inlet airfoil fans
雙入口翼截式風機On the basis of analysis previous experiment data, it is conclusion that allowable value of drift angle of elastic and elastic - plastic is 1 / 550 and 1 / 75 respectively, which is applicable to r. c. frame structure with special - shaped column is given out. the conclusion explains that the deformabiliry of r. c. frame structure with special - shaped column lies between rectangle column frame structure and shear wall structure. the calculating formula of allowable value of axial load ratio of special - shaped column is derived, it is compared with that of equaling areas rectangle column
根據對前人試驗數據的統計分析,給出了適用於異形柱框架結構的彈性和彈塑性層間位移角限值分別為1 550和1 75 ;指出了異形柱框架結構的層間變形能力介於普通矩形柱框架結構和剪力墻結構之間;以t形柱為例,推導了異形柱軸壓比限值的計算公式,通過與等面積矩形柱的對比分析,認為異形柱的軸壓比限值與其截面尺寸的比例關系有關;當腹板受壓或翼緣受壓時, t形柱軸壓比限值存在較大差異;不同的荷載角作用,軸壓比限值變化較大;矩形柱的軸壓比限值要大於異形柱的軸壓比限值。分享友人
