摘要
基于有限元分析的离散模型,将离散微分几何领域的最新成果运用于膜结构设计,求解曲面曲率,法向量,主方向及测地线,进行结构分析设计。算例表明此方法快速简便,避免多次曲面拟合。
The newest application of discrete differential geometry to the design of membrane structure is presents in this paper. It is based on the discrete model of finite analysis to get curvature, normal vector, main direction and geodesic curve, then to analyze and design the structure. The example shows the approach is quick and convenient and multiple surface fitting is avoidable.
