摘　　要：首先介绍了张力膜结构找形分析的基本原理,然后讨论非线性有限元法中的几种索单元和膜单元力学模型,并建立相应的几何方程、物理方程和平衡方程,最后提出以极小曲面作为找形分析的最终平衡状态。Firstly, the principle of form-finding analysis of tensile membrane structures is introduced in this paper. Secondly, several mechanical models of the cable element and the membrane element using nonlinear finite element are discussed, and the geometric equations, physical equations and equilibrium equations corresponding are built. In the end, the minimal surface is equilibrium state in form-finding analysis that is presented.
