【摘要】：变胞机构是由英国伦敦大学的戴建生与Ree Jones于1998年在亚特兰大召开的ASME第25届机构学双年会上提出的。变胞机构是一种可高度展开、折叠的机构,具有构态变化和自动组合等特点,能在不同的状态下改变机构有效杆件的数目从而提供不同的自由度数,自动组合出新的机构,以适应不同功能的需要。本文首先阐述了变胞机构概念和变胞原理,运用约束图和邻接子矩阵描述变胞机构构态变换的过程。并阐述了利用邻接子矩阵进行变胞机构结构分析与综合的方法,给出了机构综合及机构分析的实例来验证方法的正确性。其次,对变胞机构的应用做出阐述,并以两个变胞机构实例为例进行了说明。再次,文章对变胞机构的同构现象进行了研究,提出了一种新的基于邻接子矩阵的机构同构判定方法。并运用两个同构的10杆机构运动链为例验证了该方法。最后论文运用C++语言进行了变胞机构分析与结构综合软件的编制与开发,实现了变胞机构的自动结构分析和结构综合,并对程序运行结果进行了验证,得到了正确的结果。
[Abstract]:Metamorphosis was proposed by Dai Jiansheng of the University of London and Ree Jones at the 25th Annual meeting of ASME institutions held in Atlanta in 1998. Metamorphic mechanism is a kind of mechanism that can be expanded and folded in height. It has the characteristics of structure change and automatic combination. It can change the number of effective members of the mechanism in different states so as to provide different degrees of freedom and automatically combine the new mechanism. To meet the needs of different functions. In this paper, the concept of metamorphic mechanism and metamorphic principle are introduced, and the process of structural transformation of metamorphic mechanism is described by using constraint graph and adjacent submatrix. The method of structure analysis and synthesis of metamorphic mechanism by using adjacent submatrix is expounded, and an example of mechanism synthesis and mechanism analysis is given to verify the correctness of the method. Secondly, the application of metamorphic mechanism is expounded, and two examples of metamorphic mechanism are given. Thirdly, the isomorphism of metamorphic mechanism is studied, and a new method based on adjacent submatrix is proposed to determine the isomorphism of metamorphic mechanism. The method is verified by two isomorphic kinematic chains of 10-bar mechanism. Finally, the software of metamorphic mechanism analysis and structure synthesis is programmed and developed with C language, and the automatic structure analysis and structure synthesis of metamorphic mechanism are realized. The results of program operation are verified and the correct results are obtained.
