摘要

弹性椭圆或中心椭圆长期以来一直用于图形静力学来捕捉结构元件的弹性行为。本文从维数和退化二次曲线的可能性两个方面对这一概念进行了推广。给出了这些二次曲面的投影变换的效果，使得整个机械系统可以在变换时保持平衡和各元素之间的相容性。

Structural parts as quadrics: Elasticity ellipses revisited

Elasticity ellipses or central ellipses have been long used in graphic statics to capture the elastic behaviour of structural elements. The paper gives a generalisation the concept both in dimensions and in the possibility of degenerate conics/quadrics. The effect of projective transformations of these quadrics is also given, such that the entire mechanical system can be transformed preserving equilibrium and compatibility between its elements.

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.
