用标准零件重用设计连杆机构，兼顾性能与环保。
ReLink: Computational Circular Design of Planar Linkage Mechanisms Using Available Standard Parts
- 从现有标准件库生成可复用的连杆机构
- 通过优化匹配用户指定运动轨迹
- 适合关注可持续机械设计的研究者
循环经济强调通过组件和材料的重复利用来减少资源消耗和废弃物。本文提出ReLink，一种基于可用标准件的平面连杆机构循环设计计算框架。与多数假设可定制零件和无限供应的传统设计方法不同，ReLink优先考虑离散标准化组件的再利用，从而减少新零件需求。该框架包含两个核心部分：设计生成，通过生成算法从现有零件库存中构建机制；逆向设计，采用优化方法寻找符合用户定义轨迹曲线的设计。论文还分析了引入新零件时运动性能与碳足迹之间的权衡。针对设计问题的组合性质及有效解约束等挑战，提出了相应解决策略。通过将可持续性原则与运动学综合相结合，ReLink为计算式循环设计研究奠定了基础，助力可复用组件融入机械产品开发。
原文摘要 · Abstract (English)
The Circular Economy framework emphasizes sustainability by reducing resource consumption and waste through the reuse of components and materials. This paper presents ReLink, a computational framework for the circular design of planar linkage mechanisms using available standard parts. Unlike most mechanism design methods, which assume the ability to create custom parts and infinite part availability, ReLink prioritizes the reuse of discrete, standardized components, thus minimizing the need for new parts. The framework consists of two main components: design generation, where a generative design algorithm generates mechanisms from an inventory of available parts, and inverse design, which uses optimization methods to identify designs that match a user-defined trajectory curve. The paper also examines the trade-offs between kinematic performance and CO2 footprint when incorporating new parts. Challenges such as the combinatorial nature of the design problem and the enforcement of valid solutions are addressed. By combining sustainability principles with kinematic synthesis, ReLink lays the groundwork for further research into computational circular design to support the development of systems that integrate reused components into mechanical products.
