摘要

近几十年来,新一代空间结构的发展被称为自由空间结构。在这个新的空间结构族中,由于结构的几何性质,构件在接头内的方向变化很大,这意味着构件需要以不同的角度连接到接头。这些角度在整个结构中的广泛分布将显著影响制造成本。因此,准确、自动地计算连接角及其优化一直是研究人员和制造商感兴趣的问题。本文有以下两个主要目标。第一个目标是提供几何计算,并获得单层格构空间结构的连接角。第二个也是更重要的目标是回顾现有的方法,并开发一种用于其优化的几何方法,在本文中称为“节点定向优化”方法。利用上述方法,对一些自由形式的格点空间结构进行了一系列优化,并对结果进行了研究。

Optimized orientation of jointing system in free-form lattice space structures
The recent decades have witnessed the development of a new generation of space structures called free-form space structures. In this new family of space structures, due to the geometric nature of the structure, the orientation of the members varies substantially within the joints, meaning that the members need to be connected to the joints at different angles. The wide distribution of these angles throughout the structure will significantly affect the cost of fabrication. Therefore, accurate and automatic calculation of connection angles and their optimizations have always been of interest to researchers and manufacturers. This article has the following two main objectives. The first objective is to provide geometric calculations and obtain the connection angles of single-layer lattice space structures. The second, and more important objective is to review the existing methods and to develop a geometrical method for their optimization, referred to as the “node orientation optimization” method throughout this article. Using the mentioned method, a series of optimizations are carried out in a number of free-form lattice space structures and the results are studied.

期刊介绍: The aim of the journal is to provide an international forum for the interchange of information on all aspects of analysis, design and construction of space structures. The scope of the journal encompasses structures such as single-, double- and multi-layer grids, barrel vaults, domes, towers, folded plates, radar dishes, tensegrity structures, stressed skin assemblies, foldable structures, pneumatic systems and cable arrangements. No limitation on the type of material is imposed and the scope includes structures constructed in steel, aluminium, timber, concrete, plastics, paperboard and fabric.
