Abstract Kresling pattern origami-inspired structural design has been widely investigated using its bistable property and the single coupling degree of freedom (DOF). In order to obtain new properties or new origami-inspired structures, it needs to innovate the crease lines in the flat sheet of Kresling pattern origami. Here, we present a derivative of Kresling pattern origami—multi-triangles cylindrical origami (MTCO) with tristable property. The truss model is modified based on the switchable active crease lines during the folding motion of the MTCO. Using the energy landscape obtained from the modified truss model, the tristable property is validated and extended to Kresling pattern origami. Simultaneously, the high stiffness property of the third stable state and some special stable states are discussed. In addition, MTCO-inspired metamaterials with deployable property and tunable stiffness, and MTCO-inspired robotic arms with wide movement ranges and rich motion forms are created. These works promote research on Kresling pattern origami, and the design ideas of the metamaterials and robotic arms play a positive role in improving the stiffness of deployable structures and conceiving motion robots.

摘要Kresling 圖案折紙啟發(fā)的結(jié)構設計利用其雙穩(wěn)態(tài)特性和單耦合自由度 (DOF) 得到了廣泛的研究。為了獲得新的性能或新的折紙結(jié)構，需要對克雷斯林圖案折紙平板中的折痕線進行創(chuàng)新。在這里，我們提出了 Kresling 模式折紙的衍生形式——具有三穩(wěn)態(tài)特性的多三角形圓柱折紙（MTCO）。桁架模型根據(jù) MTCO 折疊運動期間可切換的活動折痕線進行修改。使用從修改后的桁架模型獲得的能量景觀，驗證了三穩(wěn)態(tài)特性并將其擴展到 Kresling 圖案折紙。同時還討論了第三穩(wěn)定態(tài)的高剛度特性和一些特殊的穩(wěn)定態(tài)。此外，還創(chuàng)建了具有可展開特性和可調(diào)剛度的受MTCO啟發(fā)的超材料，以及具有寬運動范圍和豐富運動形式的受MTCO啟發(fā)的機械臂。這些工作推動了Kresling圖案折紙的研究，超材料和機械臂的設計思想對于提高可展開結(jié)構的剛度和構想運動機器人起到了積極的作用。 |
