剪式机构作为可展开结构广泛应用于工业产品、建筑和航空航天结构中。一般来说，管形升降机构（TSM），由剪刀状元件组成的周围小平面，共线延伸，作为升降机，桅杆和桥梁。此外，弯曲的TSM可以形成圆拱，用作空间框架和空间天线。然而，以前的研究提出了有限的配置TSM模型，并没有提出详细的几何公式。本文提出了一种新的组合物的弯曲TSM，可以通过二维缠绕或扭曲三维延伸。详细的几何公式的剪刀状元素的解析推导，以产生各种扩展的形状。除了使用3D CAD进行数值模拟外，还组装了物理模型，以验证其可展开性，考虑到杆和接头的实际尺寸。这项工作拓宽了可扩展剪刀机构的可展开性，这最终将扩大这种结构在实际应用中的用途。
Scissor mechanisms are used as deployable structures in industrial products, architecture, and aerospace structures. In general, tubular scissor mechanisms (TSMs), composed of scissor-like elements on their surrounding facets, extend collinearly to serve as lifters, masts, and bridges. Furthermore, curved TSMs can form circular arches to serve as spatial frames and space antennas. However, previous studies proposed limited configurations of TSM models and did not present detailed geometrical formulations. This paper presents new compositions of curved TSMs that can extend by winding two-dimensionally or twisting three-dimensionally. Detailed geometrical formulations of the scissor-like elements were analytically derived to generate a variety of extended shapes. In addition to the numerical simulations using 3D CAD, physical models were assembled to verify their deployability considering realistic sizes of bars and joints. This work widens the deployability of extendable scissors mechanisms, which will eventually broaden the usage of this structure in practical applications.
