Most existing treatments for origami-folding simulations have focused on regular-shaped configurations. This article aims to introduce a general strategy for simulating and analyzing the deformation process of irregular shapes by means of computational capabilities nowadays. To better simulate origami deformation with folding orders, the concept of plane follow-up is introduced to achieve automated computer simulation of complex folding patterns, thereby avoiding intersection and penetration between planes. Based on the evaluation criteria such as the lowest storage energy with tightening and the fastest pace from tightening to unfolding, the optimal crease distribution patterns for four irregular (‘N’-, ‘T’-, ‘O’-, and ‘P’-shaped) origami configurations are then presented under five candidates. When the dimensions of the origami are fixed, it is discovered that simpler folding patterns lead to faster deformation of the origami configuration. When the folding complexity is fixed, higher strain energy results in more rapid origami expansion.

大多数现有的折纸折叠模拟处理方法都集中在规则形状的配置上。本文旨在介绍一种利用当今计算能力来模拟和分析不规则形状变形过程的通用策略。为了更好地模拟具有折叠顺序的折纸变形，引入平面跟随的概念，实现复杂折叠图案的自动化计算机模拟，从而避免平面之间的交叉和穿透。根据收紧时存储能量最低、收紧到展开速度最快等评价标准，得出四种不规则（“N”-、“T”-、“O”-、“P”）的最佳折痕分布模式然后在五个候选下呈现出“形状”的折纸配置。当折纸的尺寸固定时，人们发现更简单的折叠图案会导致折纸结构更快的变形。当折叠复杂度固定时，应变能越高，折纸展开越快。
