【摘要】：近年来，机构结构学的研究取得了巨大的进展，大批各种构件数和自由度数的机构运动链被综合出来，使机构的结构类型综合及其优选研究取得了革命性的变化。然而随着现代高科技的发展，，现有的各类简单机构已不能满足设计要求。这就迫使我们研究具有复杂结构构型机构的结构综合方法。具有可分离结构的机构是一类非常重要的机构，如在航空航天领域、复杂机器人领域、以及大型工程机械等领域得到了广泛应用。然而现有的结构类型方法很少涉及这类机构的综合，因此研究平面可分离结构运动链结构类型综合理论和开发相应的综合软件对机构学创新设计有着重要意义。本文首先介绍了机构拓扑综合的基本术语及概念，运动链的结构简图、拓扑图及其矩阵表示，然后简述了可分离运动链的基本理论以及与图论相关的基本概念。进而提出了一种新的拓扑图顶点对称性判别算法。基于闭环运动链图谱库，运用拓扑图的顶点对称性判别算法，对平面不可分离运动链进行机构综合，最后运用VisualC++程序设计语言，开发出了平面不可分离运动链机构图的综合软件。运用平面可分离运动链的相关理论以及拓扑图的顶点对称性判别算法，基于闭环运动链图谱库提出了一种平面可分离运动链自动综合的方法，这种方法不需要进行复杂的同构判别。基于已得到的闭环运动链图谱库，运用Visual C++6.0平台的可视化编程环境，开发出了平面可分离运动链拓扑图综合的软件。
[Abstract]:In recent years, great progress has been made in the study of mechanism structure, and a large number of kinematic chains of various components and degrees of freedom have been synthesized, which has revolutionized the study of structural type synthesis and optimal selection of mechanisms. However, with the development of modern high-tech, the existing simple mechanisms can not meet the design requirements. This forces us to study the structural synthesis method of the mechanism with complex structure. The mechanism with detachable structure is a kind of very important mechanism, such as aerospace field, complex robot field, large engineering machinery and so on. However, the existing methods of structural types rarely involve the synthesis of such mechanisms. Therefore, it is of great significance to study the synthesis theory of the kinematic chains of planar separable structures and to develop the corresponding comprehensive software for the innovative design of mechanisms. In this paper, the basic terms and concepts of mechanism topology synthesis, the structure diagram, topology graph and matrix representation of kinematic chain are introduced, and then the basic theory of separable kinematic chain and the basic concepts related to graph theory are briefly introduced. Furthermore, a new vertex symmetry discriminant algorithm for topological graphs is proposed. Based on the closed loop kinematic chain atlas library and the vertex symmetry discriminant algorithm of topological graph, the mechanism synthesis of planar inseparable kinematic chain is carried out. Finally, VisualC programming language is used. A comprehensive software of planar inseparable kinematic chain mechanism diagram is developed. Based on the theory of planar separable kinematic chain and the vertex symmetry discrimination algorithm of topological graph, a method of automatic synthesis of planar separable kinematic chain is proposed based on the closed loop kinematic chain atlas library. This method does not require complex isomorphism discrimination. Based on the closed loop kinematic chain atlas library and the visual programming environment of Visual C 6.0, the software of planar separable kinematic chain topology synthesis is developed.
