摘要
杂交椭球面网壳几何构造简单、结构受力合理,可改善肋环型、施威德勒型单一椭球面网壳顶点杆件连接过多及顶点附近应力集中的弊端。本文通过引入杂交型椭球面方程,采用ANSYS软件APDL参数化设计语言,研制了两类六种杂交型椭球面网壳参数化设计宏程序;并通过形状优化设计研究了其跨度、矢跨比、上部结构径向结点圈数等宏观几何参数变化对杂交型椭球面网壳受力特点的影响规律;得到一些具有工程价值的结论。
The geometrical structure of hybrid ellipsoid reticulated shells is simple and reasonable in structure,which can improve the defects of rib ring type,schweider type single ellipsoid reticulated shells and the stress concentration near the vertex. This paper introduces a hybrid ellipsoid equation using ANSYS software APDL parametric design language,the design parameters of two kinds of shell surface macro program of six kinds ofhybrid ellipsoid development. And the influence of the macroscopic geometric parameters such as the span,the span ratio and the number of the radial structure of the upper structure on the stress characteristics of the hybrid ellipsoid reticulated shell are studied by the shape optimization design. Some conclusions are given.
