折纸设计是一个新兴的领域，能够产生紧凑和高效的设计。柔性铰链被提出作为在使用非纸材料时复制纸的折叠运动的一种方式。柔性铰链起替代折叠的作用，并且可以被定义为刚度的局部减小。本文的目的是组织和评估选定的替代折叠使用的顺应机制。这些替代褶皱基于期望的运动以及通常被认为是寄生的运动来表征。此外，替代褶皱的能力，通过大偏转旋转和旋转中心的稳定性进行了评估。现有的替代折叠审查和封闭形式的解决方案。作为一个简单的设计指南打算图。指出了替代褶皱设计空间的潜在发展领域。
Origami-inspired design is an emerging field capable of producing compact and efficient designs. Compliant hinges are proposed as a way to replicate the folding motion of paper when using nonpaper materials. Compliant hinges function as surrogate folds and can be defined as localized reduction of stiffness. The purpose of this paper is to organize and evaluate selected surrogate folds for use in compliant mechanisms. These surrogate folds are characterized based on the desired motion as well as motions typically considered parasitic. Additionally, the surrogate folds' ability to rotate through large deflections and their stability of center of rotation are evaluated. Existing surrogate folds are reviewed and closed-form solutions presented. A diagram intended as a straightforward design guide is presented. Areas for potential development in the surrogate fold design space are noted.
