摘要
本文分析了常见的一维和二维剪式铰结构的几何特点和可展条件，阐述了复杂剪式铰结构的设计方法和设计原则。以抛物面壳为例，介绍了用节点坐标为未知量分析复杂剪式铰结构几何问题的方法和几何设计的步骤。求解几何问题时，文中给出了简化迭代法。
Abstract Geometric characteristics and deployable conditions of pantograph structures are introduced in this paper. Geometry design methodology and principles are also presented. Geometry analysis and design procedure of complex pantograph structures are studied with joint coordinates as variables and parabolic shell is taken as an example. Simplified iteration is employed when solving geometric equations.
