机构的概念设计在产品开发中具有重要意义，近年来引起了人们的广泛关注。然而，现有的自动化概念设计机构的方法要么容易丢失的最优解或不可扩展，以实现复杂的机构的概念设计。本文致力于开发一个全面的和可扩展的方法，自动概念设计的机构利用设计原型综合方法。为有效支持机构自动综合，将传统的形态矩阵改进为运动函数矩阵。此外，开发了机构原型知识库，为概念设计决策提供系统的知识支持。基于集成MFM，开发了一种穷举机构综合算法，以产生尽可能多的解决方案，希望的功能，以促进新的和最优的组合解决方案的发现。为了抑制穷举搜索可能导致的组合爆炸，提出了一种性能约束验证方法来帮助设计者筛选出违反性能约束的组合解，然后提出了一种基于满意度的方法来根据子解的性能来评估组合解的总体性能.开发了一个自动化机构概念设计原型系统，并通过实例验证了该方法的可行性和实用性。
Conceptual design of mechanisms has attracted a number of research efforts in recent years due to its significance in product development. However, existing approaches for automated conceptual design of mechanisms are either prone to a loss of optimal solutions or inextensible to achieve conceptual design of complex mechanisms. This paper is devoted to developing a comprehensive and extensible methodology for automated conceptual design of mechanisms utilizing a design prototype synthesis methodology. To support automated mechanism synthesis effectively, the traditional morphological matrix is improved as a motional function matrix (MFM). In addition, a mechanism prototype knowledge base is developed to provide systematic knowledge support for conceptual design decision-making. Based on the integrated MFM, an exhaustive mechanism synthesis algorithm is developed to yield as many solutions as possible to desired functions to facilitate the discovery of novel and optimal combinatorial solutions. To curb the possible combinatorial explosion from the exhaustive search, a performance constraint verification approach is proposed to help designers filter out combinatorial solutions violating performance constraints, followed by a satisfaction degree-based approach for evaluating the total performances of combinatorial solutions according to the performances of their subsolutions. An automated mechanism conceptual design prototype system is developed and a design case is presented to illustrate the feasibility and practicality of the proposed methodology.
