摘要： 研究展开过程中的折痕特性，并在弹簧质点系统基础上，提出一种基于折痕展开特性的简化分析模型，将平行折叠的柔性结构转化为折痕上的质点及连接的弹簧．分析了折痕刚度对展开的影响，给出完全展开的判定准则及通用拓扑关系，并推导了理想展开时点的运动轨迹．应用本模型对正四边形柔性结构在边框张拉受力下进行展开分析，利用自编程序通过特定功能模块实现非理想展开过程仿真．仿真展开过程与理论轨迹基本相符，验证了分析模型的合理性．并对展开过程中的受力、变形进行分析，探讨了折痕刚度对模型展开的影响．拓展了弹簧质点系统的应用范围，为柔性结构的分析、建模及仿真给出建议．

Abstract: The characteristics of creases during deployment were studied and a simple analysis model was discussed based on springmass model so that flexible structures were described by particles and springs which connected to them. Crease stiffness and the fulldeploy shape norm were studied. The topology of the creasemass model was brought up， and the motion track of perfect deployment was deduced. A case of square membrane in multistretch station was simulated though a FORTRAN program using multi modules. The deployment matches well with the perfect deployment track. The effect of crease stiffness was discussed about force and deformation. Some suggestions are brought up for analyzing and simulating flexible structures which broad up the range for spring-mass model.
Key words:  two-stage deployment    flexible structure    mass-spring system    characteristics of crease    crease-mass model    deployment simulation
