变胞机构在几何约束条件下，通过改变有效副数和杆数，可以改变机构的自由度。本文提出了一种构造6R变胞机构的新方法，并以一类具有分支运动的新机构为例进行了论证。通过串联三个班尼特连杆机构并修改所构造机构的几何参数，得到了六种新型变胞机构。这些新的机构表现出分叉运动之间的经典连杆机构，如班尼特机构，戈德堡5R机构，和变体系列戈德堡6R机构。在机构构造和建模中，定义了凸扭角，推导了基本几何约束。详细地揭示了这些变胞机构的分支变换和图形表示。
Metamorphic mechanisms are capable of changing their mobility by changing the number of effective joints and links under geometrical constraints. In this paper, a new approach in constructing 6R metamorphic mechanisms is proposed and demonstrated by a class of new mechanisms with bifurcated motion. By connecting three Bennett linkages in series and modifying geometrical parameters of the constructed mechanism, six novel metamorphic mechanisms are obtained. Those new mechanisms exhibit bifurcated motion among classical linkages such as the Bennett linkage, the Goldberg 5R linkage, and variant serial Goldberg 6R linkages. Fundamental geometrical constraints are derived with a salient kink angle being defined in the mechanism constructing and modeling. Further, the paper reveals in details the branch transformation and the graph representation of these metamorphic mechanisms.
