椭圆弧型工程曲面的研究与设计

Research and design on ellipse shape project curved surface

设计的工程曲面是以定长椭圆为母线 ,在平面上以两条互相垂直的直导线上运动而构成的 .这种曲面形状、范围完全由母线的几何形状确定 ,其工程数学特征强 ,力学工作性质好 ,构成完全理论化 .工程曲面工艺构造简单 ,施工方法容易、造型新颖 ,具有美观性及欣赏性 .这种工程曲面可用于建筑景观的屋顶设计、大型会展中心及大型体育场馆的网壳造型等 。

This paper has designed a new type of project curved surface that is from fixed length bas moving along two vertical straight lead on one surface. The type of project curved surface is decidedbythe geometril shape of the bas in the shape and range.It has the advantage of outstanding figure characters, excellent working property and all theory formation. The type of project curved surface is good at simple technological fabrication and construction method, and novel model which is pleased and appreciated. It can be used in roof design of construction landscape and reticulated shell of large stadium & gym, especially on the model and construction of large roof with many vaults.
