摘要

空间可展开机构能够通过调整其形状和大小来适应不同的操作要求。然而,目前大多数可展开机构在折叠过程中无法保持其反射表面的类型,从而限制了其调整最佳工作频率的能力。为解决这一问题,本文从叽里格米技术中汲取灵感,提出了一种具有类型保持功能的新型可展开机构设计。通过保留其反射面的类型,该装置可根据具体要求调整最佳工作频率。因此,它非常适合部署在任务不断变化的商业卫星上。该装置由多孔叽里格米单元构成,可确保在整个部署过程中保持工作表面的类型。此外,还讨论了基于多孔细胞的可部署单元和网络的构建。此外,还开发了具有可控泊松比的可展开机构。对机构的运动学进行了分析,以验证其类型保持特性。最后,还进行了四个案例研究,以说明和验证所提出的设计和分析。

Kirigami-inspired deployable mechanisms with a type-preserving feature and controllable Poisson’s ratio
A spatial deployable mechanism is capable of adapting to different operating requirements by adjusting its shape and size. However, most current deployable mechanisms fail to maintain the type of their reflective surface during the folding process, which limits their ability to adjust the optimal operating frequency. To address this issue, this paper presents a novel design of a deployable mechanism with a type-preserving feature inspired by kirigami techniques. By preserving the type of its reflective surface, this mechanism allows for the adjustment of the optimum operating frequency according to specific requirements. This makes it well-suited for deployment on commercial satellites that undergo constant mission variations. The mechanism is constructed using porous kirigami cells, ensuring that the type of the working surface is maintained throughout the deployment process. The construction of deployable units and networks based on porous cells is also discussed. Additionally, deployable mechanisms with controllable Poisson’s ratios are developed. The kinematics of the mechanism are analyzed to verify the type-preserving characteristics. Finally, four case studies are conducted to illustrate and validate the proposed design and analysis.
