具有两种工作模式的单自由度单回路机构是一种单自由度单回路机构，其作为两个不同的单自由度单回路机构工作，每个单自由度单回路机构在其两种工作模式中的一种工作模式下工作。它也被称为不连续可移动机构或向动机构。本文研究了具有两种工作模式的单自由度单回路机构的型综合问题。首先提出了一种直观的机构类型综合方法。利用所提出的方法，单自由度单回路机构，具有两个操作模式，然后使用平面4 R，球面4 R，班尼特4 R机构和/或矛盾的5 R-和6 R-机构。除了文献中提出的两类具有两种工作模式的7 R单自由度单回路机构外，还提出了16类新的6 R和7 R机构。
A single-DOF single-loop mechanism with two operation modes is a single-DOF single-loop mechanism which works as two different single-DOF single-loop mechanisms each in one of its two operation modes. It is also called a discontinuously movable mechanism or kinematotropic mechanism. This paper deals with the type synthesis of single-DOF single-loop mechanisms with two operation modes. An intuitive approach is proposed to the type synthesis of this class of mechanisms at first. Using the proposed approach, single-DOF single-loop mechanisms with two operation modes are then constructed using planar 4R, Spherical 4R, Bennett 4R mechanisms and/or paradoxical 5R- and 6R- mechanisms. In addition to the two classes of 7R single-DOF single-loop mechanisms with two operation modes proposed in the literature, 16 new classes of 6R and 7R mechanisms are proposed.
