本文根据月牙肋岔管肋板计算理论,通过分析一些已设计肋板形式,探讨了肋板边缘曲线问题。认为可用抛物线或椭圆曲线近似代替肋板内外缘曲线。从而简化了肋板设计时的计算工作,设计的肋板便于下料加工。一概述月牙肋岔管是在三梁式岔管的基础上发展起来的一种新型岔管,它以月牙形内肋板代替了笨重的外加强梁,从而使结构尺寸大为减少。由于肋板内插,有可能使作用在肋
In this paper, based on the crescent ribbed ribbed plate calculation theory, the ribbed edge curve problem is discussed by analyzing some designed ribbed forms. It is considered that the parabola or elliptic curve can be used instead of the curve of the inner and outer edges of the rib. Thus simplifying the calculation of the rib design, the ribs designed to facilitate the processing. An overview of the crescent rib bifurcation is a new type of bifurcated tube developed on the basis of the trilobal bifurcated pipe, which replaced the clunky external reinforcing beam with a crescent-shaped internal rib, thus greatly reducing the size of the structure. Due to the rib insertion, it is possible to act on the ribs
