Abstract

Compliant deployable mechanisms (CDMs), as a novel and promising type of mechanisms, have been gradually used in medical industry, aerospace and other engineering fields that require high space utilization and compactness. Therefore, it is necessary to develop a general and efficient methodology to design and analyze CDMs. This paper proposes a general framework for designing and analyzing CDMs. The proposed framework has been verified by finite element method (FEM) first. Then, for practical validation, we design two types of compliant deployable mechanisms for different application scenarios within this framework, and experimental testing has been conducted to prove the feasibility of the proposed framework. Compared to the existing methods for designing CDMs, this framework demonstrates a more general scheme where different engineering scenarios can be taken into account to meet the design requirements, presenting several desired advantages over the existing methods, such as higher accuracy and less computational expense.

通过几何精确梁理论设计顺应式可展开机构的总体框架
顺应式可展开机构(CDMs)作为一种新颖且前景广阔的机构类型,已逐渐应用于医疗行业、航空航天和其他对空间利用率和紧凑性要求较高的工程领域。因此,有必要开发一种通用、高效的方法来设计和分析 CDM。本文提出了设计和分析 CDM 的一般框架。首先通过有限元法(FEM)验证了所提出的框架。然后,为了进行实际验证,我们在此框架内针对不同的应用场景设计了两种类型的兼容可部署机构,并进行了实验测试,以证明所提框架的可行性。与现有的 CDM 设计方法相比,该框架展示了一种更通用的方案,可以考虑不同的工程场景以满足设计要求,与现有方法相比具有更高的精度和更少的计算费用等优势。
