摘　　要：基于折纸模型的二维可展板壳结构,在折叠体积较小的情况下可以获得较大的展开面积,展开效率较高.从二维折纸模型出发,研究基于此类模型的可展结构的特点,并对模型的展开过程进行分析模拟.利用Moore-Penrose广义逆矩阵的方法,结合板单元理论及相应的约束处理,对展开过程进行了计算、模拟,结合动力学方程还可以计算出展开速度和加速度.2D deployable panel and shell structure based on paper folding model could obtain large deploying area under small folding volume, whose deploying efficiency was high. Staring from 2D paper folding model, research on the characteristics of this kind of deployable structure was car- ried out, and then the deploying process of this model was simulated. By employing the Moore- Penrose general inverse matrix, combining panel unit theory and its corresponding constraints handling, the deploying process of this model was analyzed and simulated. By integrating dynam ic equations, velocity and acceleration can be computed as well.
